Stainless steel pipe heat treatment quenching equipment

Abstract

The invention provides stainless steel pipe heat treatment quenching equipment. The stainless steel pipe heat treatment quenching equipment comprises an outer cylinder, wherein a first inner cylinderand a second inner cylinder are arranged in the outer cylinder; a gap is reserved between the first inner cylinder and the inner wall of the outer cylinder to form a water inlet cavity; the second inner cylinder is arranged in the first inner cylinder, and a gap is reserved between the second inner cylinder and the first inner cylinder to form an air inlet cavity; a plurality of air nozzles are distributed on the inner wall of the second inner cylinder, inlets of the air nozzles communicate with the air inlet cavity, and outlets of the air nozzles face the axis of the air inlet cavity; a plurality of water spray nozzles are distributed on the inner wall of the first inner cylinder, inlets of the water spray nozzles communicate with the water inlet cavity, and outlets of the water spray nozzles face the axis of the water inlet cavity; and the water spray nozzles penetrate through the air nozzles and extend into the second inner cylinder. According to the stainless steel pipe heat treatment quenching equipment, water mist is adopted to quench a steel pipe, so that generation of a vapor film on the surface of the steel pipe can be reduced, radial cooling uniformity of the steel pipe is guaranteed, and the cooling speed of the steel pipe is increased.

Description

technical field [0001] The invention relates to the technical field of heat treatment of steel pipes, in particular to a quenching equipment for heat treatment of stainless steel pipes. Background technique [0002] At present, the quenching of steel pipes mainly uses the traditional quenching tank quenching method. Under this quenching method, the vapor film generated between the inner and outer walls of the high-temperature steel pipe and the quenching medium cannot be quickly eliminated, which greatly affects the quenching cooling rate of the steel pipe, and there are large differences in the cooling speed at different parts of the steel pipe, and the quenching quality is difficult. be guaranteed. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a quenching equipment for heat treatment of stainless steel tubes. [0004] A stainless steel tube heat treatment and quenching equipment ...
