Magnesium-calcium-zirconium slag non-sticking spraying coating

Abstract

The present invention relates to a calcium magnesium zirconium spray paint not adhesive to the dregs, effectively solving the problem of the high energy consumption and environmental pollution caused by the use of the paint. The present invention consists of the following weight percentage: 20 to 80 percent of dolomite, 2 to 10 percent of zirconium sand, 5 to 15 percent of corundum powder, 2 to 10 percent of microsilica powder, 2 to 5 percent of bentonite, 5 to 15 percent of soft clay, 2 to 6 percent of phosphate, 0.1 to 1 percent of calcium lignosulfonate, and 0.2 to 2 percent of boric acid;the total content is 100 percent. The tests in the steel converter show that the spray paint of the present invention has the good fluidity and can finish the spraying and compensating operation in three minutes; the present invention can effectively isolate the dregs and the deposited dregs are easy to deal with; the operational time is reduced. The main raw material used in the present invention is the non-burning dolomite containing no water; the source of the raw materials is wide and convenient; moreover, the use of the non-burning raw material can save a large amount of energy; the present invention can effectively reduce the cost and save the energy consumption.

Description

Magnesium-calcium-zirconium non-stick slag spray coating 1. Technical field The invention relates to an unshaped refractory material, in particular to a magnesia-calcium-zirconium slag-free spray coating, which is mainly used for wet gunning of a steelmaking converter. 2. Background technology Spray coating belongs to unshaped refractory material, which is a kind of refractory mixture used for gunning or spraying by jet machine, and has been widely used in the field of iron and steel metallurgy. At present, the furnace cap, trunnion, charging area, tapping hole and other parts of the steelmaking converter are mostly maintained and repaired by spraying technology. The spray coatings used include magnesium and calcium-magnesium, all of which have achieved good results. For example: the "converter tapping hole gunning material" described in CN0311564.5 is exactly a kind of magnesia spray coating used for the maintenance and repair of the tapping hole and charging area. The m...
