The method of production of electrofused zirconium corundum paving brick.Zirconium fused corundum brick paved with industrial alumina powder and zircon sand is about 66% (including 66% zirconium oxide and silicon dioxide), such as in electric furnace high temperature melting, Canon after melting casting molding, casting temperature of 1780 ~ 1840 ℃), into a model of cooling and the formation of a close to white solid, the petrographic structure composed of zirconium corundum and inclined stone

Physical and chemical indexes of fused AZS33# electrofused alumina brick by oxidation process.The zirconia corundum brick has special high resistance to the corrosion and low pollution characteristics of glass, and its performance is balanced in these two aspects. Suitable for direct contact with glass in glass melting furnace.Product application:AZS33# electrofused zirconium corundum products are mainly used in the wall of the glass kiln, the bottom of the pool, the electrode brick, the bottom

The high chromium market supply source tension support will continue to be strong.Yesterday, the purchase price of high carbon chromium iron in qingshan group in January 2018 was settled at 7296 yuan /50 basis tons, up 200 yuan /50 basis tons from last month. In 2016, qingshan group achieved 5.8 million tons of stainless steel crude steel production, sales revenue of 102.8 billion, and more than 30,000 employees. Qingshan trademark is a well-known trademark in China, so it can be used for refere

Recent trend analysis of alumina market.Since winter, affected by the coal to gas, gas supply slightly tight, part of the calcined alumina enterprises link is affected by a certain, YaChan alumina production enterprise happening in northern region, alumina production in a certain decline. But the impact on the supply of alumina is not big, but the impact on market sentiment is more. On the supply side, the monthly output of alumina has been declining due to the production of the wrong peak of he

On April 1, the environmental tax levy, the price of all kinds of raw materials will start again!From 2016 to 2017, environmental inspectors will not be able to survive the death of plastics, papermaking, printing, mining, chemicals, steel, building materials, coatings and other manufacturing enterprises. The limit of production, closure and price rise, alone in the beijing-tianjin-hebei region alone, 167,000 small and scattered enterprises have been cleaned up, and countless enterprises have di

High technology composite sealing refractories help glass kiln to live long.Glass furnace composite seal refractory series, with all kinds of high technology has been widely applied in glass industry furnace, self-closed and seal of a bottom, the wall must be adopt multi-layer sealing structure, make the glass furnace to realize absolute seal. This not only ensure the safe use of furnace, also avoid the kiln, greatly extend the service life of the furnace, and because the seal and strengthen the
