Э.В. Булин of the Russian Polovich Refractory Company introduced the current situation of the refractory industry in Russia at the International Conference of Russian Refractory Materials and Metallurgists.
He believes that for refractory materials, the trend from shaped products to unshaped refractory materials (mainly refractory castables) is a trend. The use of unshaped refractory materials can not only increase the lining life of traditional metallurgical equipment such as blast furnace, ladle, tundish, but also significantly reduce the amount of labor before the furnace and increase the speed of lining. A significant improvement in this area is the production and application of andalusite products, whose use has now expanded to cement rotary kiln, blast furnace and hot blast stove.
The future development of refractory materials mainly has the following aspects:
In the case of amorphous refractory materials, it is mainly refractory castables, used for blast furnace lining (spraying technology), blast furnace tapping iron trench, ladle and ladle lining, molten steel furnace external processing equipment, dry cement kiln external circulation Heat exchangers, as well as insulation and repair refractories.
In the aspect of shaped refractory materials, new types of clay bricks and high-aluminum bricks with high technical potential are produced: such as lining materials for some areas of cement kiln, flow steel bricks, refractory bricks for blast furnaces and hot blast stoves, red for blast furnaces and hot blast stoves Column stone brick, anode baking furnace products, clay and high aluminum heat insulation bricks, etc.
Regarding the problem of rising raw material prices and increasing production costs of refractory materials in recent years, he believes that in order to produce refractory products that meet user requirements, high-purity mineral raw materials with low impurity content must be used. This type of raw material is relatively scarce in Russia. Secondly, it should be said that such raw materials are not only needed by the refractory industry, but also required by adjacent industries, and even more urgent. The main reason for the price increase is the lack of supply, the depletion of old mines and the lack of newly developed mines, which has deepened this lack. Russia lacks high-quality raw materials and chemical additives for the production of refractory materials, so it must be imported from abroad. Refractory manufacturers have to make up for the shortcomings of raw materials, and part of them rely on mobile storage materials. On the one hand, they expand the list of alternative raw materials and their suppliers. However, due to the special process requirements for refractory raw materials, this measure is sometimes not It works.
The basic development direction of the Russian refractory market is inseparable from the international development trend: the production of amorphous refractory materials develops at a certain growth rate, firstly castables, and innovative refractory products are produced. The use of these refractories in thermal equipment linings ensures improved technical and economic performance. The company's production strategy depends on the prediction of the development of the refractory products and services market in Russia and the CIS countries. To further modernize the existing process, give priority to the development of new products and services that customers demand, and establish flexible production lines to enable them to adjust production according to user orders. They can produce small batches of products as well as large quantities of products. Its own raw material base, including the use of old mines, and promotion of energy-saving processes. Having the company's own technology and production improvement center is a key factor in the success of the innovation and promotion process. Its mission is to research and produce new refractory products, providing technical and process support throughout the product's cycle.
