Non-oxidation differential temperature quenching heat treatment equipment for abrasion-resisting cement roller shell

Abstract

The invention discloses non-oxidation differential temperature quenching heat treatment equipment for an abrasion-resisting cement roller shell and relates to the technical field of roller shell differential temperature heat treatment. The non-oxidation differential temperature quenching heat treatment equipment for the abrasion-resisting cement roller shell comprises a cylindrical protective shield, an antioxidant, a protective cover, a cylindrical profiled furnace shield, a heating element and a trolley, wherein the protective shield surrounds the cement roller shell, the protective shield and the cement roller shell are coaxially arranged, the antioxidant is arranged between the protective shield and the cement roller shell and makes contact with the outer surface of the side wall of the cement roller shell, the cement roller shell is covered with the protective cover, the profiled furnace shield surrounds the protective shield, the profiled furnace shield and the cement roller shell are coaxially arranged, the heating element is arranged on the internal side wall of the profiled furnace cover, and the profiled furnace shield, the cement roller shell and the protective cover aresupported by the trolley; and the height of the cement roller shell is identical with that of the protective shield, and a certain space is arranged between the protective shield and the profiled furnace shield. The equipment which can prevent cement roller shell surface oxidation and can also achieve differential temperature heat treatment of the cement roller shell is provided for the defects of an ordinary trolley furnace treating the abrasion-resisting cement roller shell.

Description

technical field [0001] The invention relates to the technical field of differential temperature heat treatment of roller sleeves, in particular to a high-temperature heat treatment equipment for wear-resistant cement roller sleeves that realizes rapid heating and non-oxidation treatment. Background technique [0002] Wear-resistant cement roller sleeves are used for mining cement crushing and rolling, and the operating environment is very harsh. In order to ensure the rolling effect, the surface of the cement roller sleeve has patterns, and the extrusion between the patterns will break the large pieces of material during use. The wear-resistant cement roller sleeve is manufactured by centrifugal compounding of multi-layer materials. The composition and structure of the outer layer and the core of the wear-resistant cement roller sleeve are different. The outer layer needs high hardness and high wear resistance, and the core needs high toughness. and high strength. Therefor...

AI Technical Summary

Problems solved by technology

Ordinary trolley furnace without atmosphere protection can easily cause wear-resistant cement roller sleeves to oxidize, and the pattern will be oxidized during differential temperature treatment, causing further damage, thus affecting the final use effect of wear-resistant cement roller sleeves

At the same time, the overall heating and heating speed of ordinary trolley furnaces are limited, and differential temperature heat treatment cannot be realized.
