Embodiment Construction

[0007] In the embodiment of the present invention, after the outer diameter of the cast inner water jacket (1) is processed, its corresponding outer diameter is larger than the inner diameter of the thin-walled outer water jacket (2) of the furnace and the thin-walled outer water jacket (3) of the chimney by about 0.08 mm. , Weld the thin-walled outer water jacket (2) of the furnace to the water inlet (2) a ) and the thin-walled outer water jacket (3) of the chimney are welded on the water outlet (3) a ) and then heat it to about 300°C and put it into the corresponding part of the inner water jacket (1) while it is still hot. After the outer diameter of the cast inner water jacket (1) is processed, its corresponding outer diameter is smaller than that of the furnace thin-walled outer water jacket (2) and the chimney thin-walled outer water jacket (3) with an inner diameter of about 0.08mm. Machined with large rubber gasket grooves (1 g ) and a small rubber pad slot (1 h ) a...

Abstract

A combined water jacket of heating furnace consists of internal water jacket, thin - wall external water jacket of firepot, thin- wall external water jacket of chimney, slag catcher, large rubber pad and small rubber pad. The method for preparing combined water jacket is also disclosed.

Description

technical field [0001] The invention relates to a heating furnace water jacket, which is a combined water jacket installed in a heating furnace and a manufacturing method thereof. Background technique [0002] The "Plumbing Furnace Cast Iron Water Jacket" (patent number: 022703446) authorized by the State Patent Office on November 5, 2003 is to cast the water jacket into upper and lower parts and then connect them with bolts, although the casting water jacket is slightly simplified. However, due to the complex process of manufacturing the core, the production cost is still high, and the weight of the product has not been reduced. SUMMARY OF THE INVENTION [0003] The purpose of the invention is to simplify the molding casting process, reduce the production cost, and greatly reduce the weight of the water jacket. The technical scheme of the present invention is as follows: the water jacket of the heating furnace is divided into an inner water jacket and a thin-walled outer...
