the National Bureau of Statistics, the national cement output in 2022 was 2.13 billion tons, a sharp decline compared with the same period last year. 10. In terms of price, the national " was affected by factors such as declining demand, depressed market and high cost. In 2022, the total profit of the cement industry was about 68 billion yuan, down about 60% from the same period last year, and thousands of cement enterprises in the whole industry lost money. The trend
of the National Cement Price Index (CEMPI)
in 2022 is that "the downward trend of cement market demand is unavoidable, and the internal strength of enterprises will be tested more and more in the future". Chongqing Orient Hope Fengdu Cement (abbreviated as ") was founded in 2009, when China's cement industry was still in a period of demand growth. However, the problem of overcapacity has been highlighted, the market competition has become increasingly fierce, and the domestic cement market has become a veritable "Red Sea". However, Dongfang Hope Group still decided to build five 5000t/d cement clinker production lines in the upper reaches of the Yangtze River, relying on the confidence in its bones.
As Mr. Liu Yongxing, chairman of Dongfang Hope Group, once said: "When you really become a strong person, others will not be able to shake you." So how did Dongfang Hope Cement become a strong person?
"The price of cement 20 years ago is not much different from the price of cement now, but the house 20 years ago is much cheaper than house now." Eastern Hope 
In recent years, Dongfang hopes that Chongqing Cement will continue to intensify its technological transformation efforts, and the cost of technological transformation in 2022 alone will be close to 300 million yuan. Now, in Dongfang Hope Cement Plant, the application of new technologies can be seen in all links that can effectively reduce production energy consumption, ranging from fans, pumps, air compressors to grate coolers, vertical mills, preheaters and other main equipment, which can be called the "Exhibition Hall of Advanced Technologies in Modern Cement Industry".
Hou Jian: "We have a high degree of acceptance of new technologies, and the chairman of the group is also very supportive of our energy-saving transformation and encourages us to dare to try new things." When it comes to "dare to venture and dare to try", we have to mention the preheater "5 to 6" project implemented by Dongfang Hope Cement in 2022.
In the cement industry, most of the 5000t/d production lines are 5-stage preheaters, except for individual cement enterprises built in recent years. In recent years, with the in-depth research of preheater technology, the industry has gradually realized that 6-stage preheater has great advantages in reducing production energy consumption, but the transformation of preheater is difficult and risky. For many years, no cement enterprise has dared to try to change 5-stage preheater to 6-stage preheater. Dongfang hopes that cement industry will become the first enterprise to "eat crabs".
According to Hou Jian, Dongfang hopes that after the implementation of "5 to 6" in the preheater of Chongqing Cement 3 # production line, the energy consumption per ton of clinker will be reduced by 3kg, the C1 outlet temperature will be reduced to 260-270 degrees, the energy consumption per ton of clinker will be reduced to 96 kg of standard coal, and the overall energy consumption level will be in the forefront of the industry.
Quality priority for more than six consecutive years, zero customer complaints
, cement is known as the "food" of the construction industry, is the key to ensure the quality of the project. The "strong" in the cement industry needs not only leading cost control, but also excellent product quality.
Hou Jian said, "In the final analysis, cement is to serve downstream engineering construction, so the quality requirements must be from the user's point of view. High surplus strength does not mean good quality of cement. Relatively speaking, quality stability and adaptability are more critical. Our cement strength may not be the highest in the Yangtze River Basin." But the quality stability and adaptability must be leading.
It is understood that in Dongfang Hope Cement, the production factors include five aspects: safety, environmental protection, quality, output and cost, among which the priority of quality factors should be related to output and cost.
In order to improve the stability and adaptability of product quality, Dongfang hopes that Chongqing Cement will stabilize the composition of raw materials through advanced quality control system and online analysis of all production lines, which will play a key role in stabilizing the quality of clinker. At the same time, because Dongfang hopes that Chongqing Cement will have 2.
Based on the above reasons, Dongfang hopes that the quality indicators of Chongqing cement clinker will reach the advanced level in the industry.
Data show that the company's clinker, cement 28-day strength, standard deviation and other key quality indicators have reached the first-class level in the industry. Thanks to the emphasis on product quality, Dongfang hopes to have maintained zero complaints about quality problems for more than six consecutive years. In view of the huge capacity scale of five 5000t/d production lines and the huge market scope covering almost the whole Yangtze River Basin, it is not easy to achieve the above achievements.
With the first-class quality, first-class brand and strong comprehensive strength of the Yangtze River Basin, Dongfang Hope Chongqing Cement has participated in the construction of Zhengzhou-Wanzhou high-speed rail, Chongqing-Wanzhou high-speed rail, Chongqing Light Rail, Chongqing-Guizhou Railway, Chongqing-Li Railway and other large-scale projects.
Hou Jian: "Cement is a highly homogeneous industrial product, if we can not gain an advantage in the core issue of quality stability and adaptability, it is difficult to gain the first chance in the market competition.".
Looking forward to extending the industrial chain and accelerating the green low-carbon transformation
in the future, according to Hou Jian, in 2022, facing the test of declining demand for cement and the downturn of the industry, Dongfang hopes that cement will continue to develop new products, extend the industrial chain, and continue to promote technological upgrading and transformation. Last year, the company's production of high-quality machine-made sand and aggregate reached a record high. At the same time, the production indicators such as the standard coal consumption per ton of clinker, the comprehensive power consumption of clinker, the comprehensive power consumption of cement and the hourly output of clinker are all the best in history.
Especially in the extension of industrial chain, the company has developed and innovated thin layer mortar, dry-mixed mortar for synchronous grouting of shield tunnel, C60P6 fiber concrete, mass C30P6 concrete and mass C30P8 concrete; At the same time, from the initial clinker, cement products, to aggregate, machine sand, commercial mixing, aerated brick, aerated plate, Fengdu cement product line is also constantly enriched.
Especially in August 2022, Dongfang hopes that the trial production of Fengdu Cement PC Component Project will be a complete success, marking another success in the extension of the industrial chain. According to the data
of Dongfang Hope Cement PC Component Project
, Dongfang Hope Cement PC Component Project covers an area of about 180 mu, with a total investment of 100 million yuan, an annual output of 225000 autoclaved aerated concrete slabs and 7 autoclaved aerated concrete blocks.The project uses the company's own sandstone, cement, waste heat steam and other resources for integrated production, and adopts standardized, mechanized and intelligent processing and production. Compared with the large amount of dust, noise and other pollutants produced in the production of traditional sintered shale bricks, the company's PC component project has a significant effect on environmental protection and energy saving.
