Abstract

The present invention relates to a wear resistance casting material for ladle. The wear resistance casting material comprises, by weight, 1 part of a corundum material, 0.1-1 part of silicon carbide, 0.01-0.1 part of graphite, 0.001-0.1 part of an explosion-proof agent, 0.001-0.1 part of a composite additive, and 0.1-0.25 part of a binding agent. According to the present invention, the cement component-free inorganic nanometer binding agent is adopted, good quality electrofusion or sintering corundum or special grade alumina clinker is adopted as the main material, silicon carbide, graphite, an explosion-proof agent and the like are added, and variety and the number of a composite additive are optimized to prepare the wear resistance casting material with characteristics of rapid baking, high high-temperature strength, good high-temperature wear resistance, excellent thermal shock stability and good construction performance; and ladle bottom of the bottom washing type ladle with a capacity of one ton is used in gray iron casting, wherein the service life can be more than 3000 times and is more than two times the service life of the conventional material, and slag removing is easy.

Description

technical field

[0001] The invention belongs to the field of castables, in particular to a wear-resistant castable for ladles. Background technique

[0002] Ladles are used in the steel and foundry industries. The function of the molten iron ladle is to transfer the high-temperature molten iron flowing out of the blast furnace tapping trough, cupola chute, and electric furnace chute to the pouring process or subsequent processes. The molten iron ladle needs to be preheated with high-temperature molten iron before use, and then filled with molten iron. After being transported to the required location, the molten iron is poured out, and then returned to the front of the furnace for the next cycle of loading and unloading molten iron. During use, the ladle needs to withstand the thermal shock of hot molten iron at 1350-1500°C, molten iron erosion, molten iron wear, and thermal shock caused by drastic temperature changes. Generally, low-cement or ultra-low-cement castables are ...
