Abstract

The invention provides a drill rod heat treatment device and method for blast furnace opening, and belongs to the technical field of heat treatment. The drill rod heat treatment device for blast furnace opening comprises a support frame, a conveying mechanism and an induction coil. The conveying mechanism is fixedly mounted on the support frame, and is used for conveying drill rods; the inductioncoil is fixedly mounted on the support frame, is positioned above the conveying mechanism, and is used for being connected with inductive heating equipment to heat the drill rods on the conveying mechanism; and a spraying port is formed in the tail end of the induction coil, and is used for spraying cooling liquid to the heated drill rods for quenching. The device is simple in structure and less in occupied space, centralizes the quenching operation of the drill rods in one station for completion, greatly improves the production efficiency, and shortens the production period. The drill rod heat treatment method for blast furnace opening shortens the drill rod quenching operation time, improves the production efficiency, and can effectively remove scales on the surfaces of the drill rods toimprove the surface quality of the drill rods.

Description

technical field [0001] The invention belongs to the technical field of heat treatment, and more specifically relates to a heat treatment device and method for a drilling rod for blast furnace opening. Background technique [0002] The drilling rod for blast furnace opening belongs to a kind of metallurgical drilling tool. During the blast furnace opening operation, the impact energy and torque provided by the tapping machine need to be transmitted to the drill bit through the drill rod. mouth. [0003] Because the drill rod is in the working environment of alternating loads of impact load and torque, bending and fracture become the main failure modes of the drill rod used for blast furnace openings. In addition, since the drill rod and the drill bit are usually connected by threads, if the thread strength is not enough, the thread will fail. , directly lead to the scrapping of the drill rod. Therefore, it is very necessary to improve the hardness, strength and toughness of...
