Thermal-shock-resistant magnesia-carbon brick automatic forming equipment used for electric furnace lining

Abstract

The invention relates to the field of magnesia-carbon brick production, in particular to thermal-shock-resistant magnesia-carbon brick automatic forming equipment for an electric furnace lining. The thermal-shock-resistant magnesia-carbon brick automatic forming equipment comprises an installation column and a switch assembly, wherein two sets of installation plates are transversely arranged at the upper end of the installation column; a processing box is detachably mounted between the two sets of installation plates; the upper end of the processing box is connected with a feeding hopper; a motor box is arranged on the front surface of the processing box; a feeding opening connected with the feeding hopper is formed in the upper end of the processing box; a discharging opening is formed inthe lower end of the processing box; a rolling disc is arranged in the processing box; a connecting shaft is connected to the middle of the rolling disc in a penetrating manner; friction blocks are arranged on two sides of the processing box; two sets of heating fans are symmetrically arranged at the bottom of an inner cavity of the processing box; a fixing seat is arranged on the outer side of the processing box; and a conveying frame is mounted at the upper end of the fixing seat. According to the thermal-shock-resistant magnesia-carbon brick automatic forming equipment, an automatic feeding and blanking structure is used for replacing conventional manual operation, and a plurality of sets of die grooves in the outer side of the rolling disc cooperate with rotation of the rolling disc for automatic production, so that the integral automation degree is better, the production efficiency is higher, and the thermal-shock-resistant magnesia-carbon brick automatic forming equipment is worth of being used in the market and popularized.

Description

technical field [0001] The invention relates to the field of magnesia-carbon brick production, in particular to automatic forming equipment for thermal shock-resistant magnesia-carbon bricks used in the lining of electric furnaces. Background technique [0002] Magnesia-carbon bricks are made of high-melting-point basic oxide magnesia and high-melting-point carbon materials that are difficult to be infiltrated by slag as raw materials, and various non-oxide additives are added. A non-burning carbon composite refractory material combined with a carbonaceous binder. Magnesia carbon bricks are mainly used in the lining of converters, AC electric arc furnaces, DC electric arc furnaces, and slag lines of ladles. As a composite refractory material, magnesia carbon brick effectively utilizes the strong slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon to compensate for the biggest shortcoming of magnesia's poor spalling resistance. ...

AI Technical Summary

Problems solved by technology

[0003] The production of magnesia-carbon bricks requires special molding equipment for extrusion molding, but the existing automatic molding equipment has many technical defects: its feeding is mostly manual operation, which wastes unnecessary manpower while the degree of automation is low; On the other hand, its production efficiency is low during molding, which affects the final output
