Compared with prior art, high-efficiency and precision binary channels high temperature tunnel furnace of the present invention has the following advantages that:
Continuous tunnel furnace is divided into two up and down, independent simultaneously can carry out heat treatment process, and continuous tunnel furnace is divided into high-temperature baking area and cold But area's two parts form.High-temperature baking divides into 3 sections of controls, and three sections are kept in different temperatures section, and temperature edge is sent Part direction successively reduces.Strength cooling device is equipped in cooling zone.
Four sand blasting units are installed in the upper goods area for being located at conveying mechanism front end, are located at continuous tunnel furnace surrounding, automatically to upper Goods area aluminum alloy materials carry out bead.
Continuous tunnel furnace specific structure is:Using boom bar chain as conveying device, gear work is respectively adopted in two rows of separate tunnels For driving wheel and follower, conveys power and uses horizontal gearmotor, be equipped with frequency converter, be mounted at left and right sides of head, Speed is adjustable.Boom chain supporting bar is made using angle steel, enhances security performance.
The specific structure of upper and lower two continuous tunnel furnaces is:On just logical bracket, by keeping apart two between two separate tunnel furnaces Tunnel, furnace internal-lining and shell difference thermally conductive materials guarantee heat insulation effect, plastic-spraying processing.
Three stage control toasts mechanism, and by delivery direction, temperature range is gradually decreased, and provides heat using high-power heat-generating pipe Source reaches predetermined temperature, controls temperature using stages cycle blower device operating power.And pass through three sections of heat-generating pipes of independent control With the power of circulating blast device, every section of continuous tunnel furnace temperature range is controlled.
Toasting the strength cooling device in mechanism controls cooling zone is air-cooled air curtain, and arranges pumping system using hot wind, will Discharge hot wind is connect with user's exhaust system.
