The main problems of new dry process kiln refractory materials

(1) Refractory material inner quality is not stable and the size of irregularity is a serious problem in the whole industry. The main reason is that the level of equipment for producing refractory material is too low, the management problems of the production is also more. Neither series manufacturing refractory equipment factory supply meet the transformation requirements of fixed-point production equipment, refractories enterprises benefit and decreased year by year, outdated equipment, the lack of its own functional improvements, unable to carry out technical transformation.

(2) The cement factory on refractory material selection and storage also has many problems, some kiln equipment and process many problems, even frequent stop kiln. Therefore, only a handful of kiln, the world’s advanced level of refractory material unit consumption reached 0.6-0.8kg / T, generally deviate a lot.

(3) The new dry process kiln refractory materials production capacity at present more than 10000 tons, but cannot satisfy the kiln; needs development, must have the correspondingexpansion.

(4) in recent years abroad new dry process kiln lining tends to be light, is light and ultra light materials to improve the quality, the use of an increase in the proportion of the kiln lining, the total weight of about minus 20%, further open the gap between us and them.

(5) In foreign countries are promoting the use of low chromium (Cr2O3 < 4%)magnesia chrome brick, and on the development of chrome free basic bricks of high quality. China is lack of chrome ore resources of the country, to high quality alkaline brick rapid development and production of low chromium or chromium free, can also help to reduce the chromium pollution on the environment.
