Embodiment 1
[0018] A method for manufacturing a special thermal insulation door and window for a grain depot, the specific manufacturing steps are as follows:
[0019] Step 1: Recycling scrap iron and steel, performing derusting treatment, sending the derusted iron and steel into an electric furnace for smelting, and performing dephosphorization treatment, adding alumina during the smelting process to obtain alloy liquid.
[0020] Step 2: The alloy liquid obtained in Step 1 is poured under the protection of argon gas, and poured into a door panel steel alloy steel casting, and the steel alloy steel casting is a cover plate for the inner panel and the panel.
[0021] Step 3: Etching the steel alloy steel casting obtained in Step 2 by chemical microetching, so that the surface has etched micropores.
[0022] Step 4: Put titanium dioxide, silicon dioxide, aluminum oxide, copper and nickel through a jet mill for air dry classification, make titanium dioxide, silicon dioxide, aluminum oxide, c...

Abstract
The invention discloses a manufacturing method for a heat preserving door and window special for a grain depot. The method includes the following special manufacturing steps that firstly, waste steeland iron are recycled, and are subjected to rust removing treatment, the steel and iron after the rust removing treatment are fed into an electric furnace to be smelted, and are subjected to dephosphorization treatment, and aluminum oxide is added in the smelting process so that alloy liquid is obtained; secondly, the alloy liquid obtained in the first step is subjected to casting through argon protection, and is cast into a steel alloy steel casting of a door plate or a window frame, and the steel alloy steel casting is a covering combined plate of an inside plate and a face plate; and thirdly, the steel alloy steel casting obtained in the second step is subjected to etching treatment due to chemical micro etching, so that the surface of the steel alloy steel casting has etching micro holes. Due to plating and coating of ultrafine powder, the surface of the door and window has extremely high corrosion resisting and high temperature resisting characteristics, and the combining force ofa copper plating layer of the surface of the door and window casting is higher, and therefore the service life of the door and window is effectively prolonged, the oxidization resisting effect is better, the door and window has good fireproof characteristic while heat preservation is achieved, and the external protecting performance of the grain depot for use is better.
Description
technical field [0001] The invention belongs to the technical field of thermal insulation doors and windows, and in particular relates to a method for manufacturing thermal insulation doors and windows dedicated to grain depots. Background technique [0002] The existing thermal insulation doors and windows for grain depots have a short outdoor service life, do not have a protective layer with good bonding force and oxidation resistance, and the material cost is high. Without excellent protective properties, the overall is relatively bulky. For this reason, We propose a method for manufacturing special thermal insulation doors and windows for grain depots. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing special thermal insulation doors and windows for grain depots, so as to solve the problem that the existing thermal insulation doors and windows for grain depots proposed in the background art have a short outd...
