A roller bottom heating furnace for casting and spinning aluminum alloy wheels

Abstract

The present invention discloses a cast-spun aluminum alloy wheel roll bottom heating furnace, comprising a stick machine and a furnace body, wherein the stick machine is mounted on the outer wall of the furnace body near the lower end, and a heating chamber is arranged inside the furnace body. The transmission material and the material preparation table are fixedly connected by a material placement groove, and the material placement groove facilitates the transmission material to be placed inside an inner box for restraint and fixation. Since the inner box and the outer box are fixedly connected by a buffer spring, the good elasticity of the buffer spring can be utilized to greatly buffer and offset the collision force on the transmission material when the transmission material is being transported or placed, so as to protect the transmission material. The transmission material can be conveniently conveyed by the action of nine rotating rods equidistantly distributed on the upper end of the ladder platform. After the transmission material is conveyed to the top material device, the transmission material is pushed by a telescopic shaft driven by a motor, and the transmission material is pushed onto the stick machine for transmission.

Description

Technical Field

[0002] In the metallurgical industry, a heating furnace is a device that heats materials or workpieces to rolling or forging temperatures. Heating furnaces are used in a wide range of industries, including petroleum, chemical engineering, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals. The furnace's structure is divided into three sections along its length, based on the temperature distribution. The preheating section, located at the feed end with a lower temperature, utilizes the heat from the furnace gas to improve the furnace's thermal efficiency. The heating section is the primary heating section, with higher gas temperatures to facilitate rapid heating. The soaking section, located at the discharge end, minimizes the difference between the gas temperature and the metal charge temperature, ensuring uniform cross-sectional temperature of the discharged billet. Heating furnaces include continuous heating furnaces and chamber heating furnaces. Heating furnaces used for metal heat treatment are also known as heat treatment furnaces. A furnace that heats steel ingots before initial rolling or makes the internal temperature of the steel ingots uniform is called a soaking furnace. In a broad sense, heating furnaces also include soaking furnaces and heat treatment furnaces. Among them, continuous heating furnaces include pusher-type heating furnaces, walking-beam furnaces, rotary hearth furnaces, chamber furnaces and other continuous heating furnaces, but pusher-type furnaces are usually referred to.
