Formula and manufacturing method of slag ladle trunnion anti-sticking steel sheath

Abstract

The invention discloses a formula and a manufacturing method of a slag ladle trunnion anti-sticking steel sheath, which relate to the technical field of casting residue treatment. According to the formula of the slag ladle trunnion anti-sticking steel sheath, the formula comprises 60-90% of slag, 5-30% of lime, 5-10% of a binder and the balance of a refractory material, and the refractory material is a mixture formed by mixing CaO and Al2O3 according to the proportion of 3: 1-6: 1. According to the formula and the manufacturing method of the slag ladle trunnion anti-sticking steel sheath, the matched trunnion sheath is manufactured, the sheath is placed at the position of the trunnion when the slag ladle receives slag steel, and the sheath is taken down when the slag ladle is hoisted. The formula effectively prevents slag steel from being adhered to the trunnion when the steel ladle is turned over casting residues, so that the lifting of the slag ladle is prevented from being influenced, the casting residue slag steel in the steel ladle is effectively prevented from being adhered to form a weight at the trunnion in the pouring process, so that the phenomenon that a slag ladle lifting appliance cannot be completely clamped into the trunnion for lifting the slag ladle is prevented, smooth production is ensured, and the hidden danger of pouring the slag ladle caused by the weight of the slag steel adhered to the trunnion of the ladle is reduced.

Description

technical field [0001] The invention relates to the technical field of casting slag treatment, in particular to a slag tank trunnion anti-sticking steel sheath formula and a manufacturing method thereof. Background technique [0002] Casting slag is the mixture of molten steel and slag left after the molten steel in the ladle is continuously cast or ingot cast. [0003] In terms of casting slag treatment, the treatment modes of all major steel mills are basically the same. They all use the crane to hang the ladle directly into the slag tank. The trunnion is bonded into a mound, so that the slag tank spreader cannot be completely stuck in for lifting the slag tank, which affects the production rhythm and poses a great safety hazard.

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a slag pot trunnion anti-stick steel sheath formula and its manufacturing method, which solves the problem of casting slag treatment. Turn the ladle directly into the slag pot. During the process of dumping the remaining steel slag, part of the steel slag will fall into the trunnion of the slag pot. Lifting, affecting the production rhythm, there are great safety hazards
