Matched structure of cooling device of intermediate frequency furnace for heating steel bar and steel ball quenching device

Abstract

The invention relates to a matched structure of a cooling device of an intermediate frequency furnace for heating a steel bar and a steel ball quenching device and belongs to the technical field of quenching facilities of metal pieces. The cooling device of the intermediate frequency furnace for heating the steel bar comprises a liquid quenching medium conveying pipe, wherein a blowdown connector is matched and connected on the lower part at the left end of the liquid quenching medium conveying pipe, a liquid quenching medium introducing connector is matched and connected to the upper part at the right end of the liquid quenching medium conveying pipe, and a liquid quenching medium output pipe connector is arranged on the middle part; the liquid quenching medium output pipe connector is provided with a control valve, a left seal cover is arranged at the left end, a right seal cover is arranged at the right end, a cavity of the liquid quenching medium conveying pipe is provided with a heat exchange pipe, a left seal cover connector is arranged on one side, back on to the left seal cover cavity, of the left seal cover and a right cover connector is arranged on one side, back on to the right seal cover cavity, of the right seal cover; a cooling liquid circulating mechanism is connected between the left and right seal cover connectors, and the control valve is connected with one end of the liquid quenching medium output pipeline; and the steel ball quenching device comprises a quenching tank. The intermediate frequency furnace does not need to be cooled by using a cooling tower, so that the intermediate frequency furnace is durably clean, the cost is lowered, the electric consumption and liquid are saved, and the work stability is ensured.

Description

technical field [0001] The invention belongs to the technical field of quenching facilities for metal parts, and in particular relates to a matching structure between a cooling device of an intermediate frequency furnace for heating steel rods and a steel ball quenching device. Background technique [0002] The steel rod mentioned above refers to the steel round bar, and the steel ball mentioned above refers to the steel ball obtained by rolling the steel ball rolling machine after being heated by the intermediate frequency furnace. [0003] Take the building material production industry such as cement manufacturers as an example. In the process of cement production, the ore crushed by the crusher in the previous process needs to be ball milled (the industry is accustomed to call it grinding), and ball milling requires a large amount of wear resistance. , Steel balls with excellent toughness. The production process of steel balls is as follows: heating the bar (that is, ste...
