Problems solved by technology

The furnace bottom of the trolley-type heat treatment furnace can be moved and tilted, and it is convenient to directly transport the heat-treated castings from the heating chamber to a destination such as a quenching tank, and then tilt and unload them. However, the furnace of the trolley-type heat treatment furnace The door is not well sealed, and the temperature here is uneven, so the heat preservation performance of the trolley heat treatment furnace is not good, which will adversely affect the physical properties of the casting after heat treatment
[0005] Therefore, neither the traditional car-type heat treatment furnace nor the traditional bell-type heat treatment furnace can fully meet the current requirements for low energy consumption, high heat preservation and high work efficiency of periodic heat treatment furnaces.

Abstract

The invention discloses a bogie type heat treatment furnace. It includes furnace mantle, travel mechanism, and furnace bottom. Its features are that the furnace mantle and the bottom are formed sealed heating chamber; it also includes furnace mantle elevating mechanism. The invention can save power utilization, ensure casting heat treatment quality, reduce labor intensity, and increase production efficiency.

Description

technical field [0001] The invention relates to a heat treatment furnace, in particular to a trolley type heat treatment furnace. Background technique [0002] With the rapid development of my country's foundry industry, the market competition among casting manufacturers is becoming more and more fierce. For casting manufacturers, only high-quality and low-consumption castings can have market competitiveness. Heat treatment is the key factor that determines the performance and production process of castings. One of the important processes of energy consumption, the heat preservation effect and working efficiency of the heat treatment furnace used in heat treatment directly affect the physical properties of castings and the production efficiency of castings. [0003] Traditionally used periodic heat treatment furnaces include bell-type heat treatment furnaces and trolley-type heat treatment furnaces, etc. For traditional bell-type heat treatment furnaces, it includes a furnace...
