Abstract
The utility model discloses thermal treatment equipment of a tool joint. The thermal treatment equipment comprises a quenching heating furnace, heat insulating equipment connected with the quenching heating furnace and a cooling tank connected with the heat insulating equipment, wherein the temperature in the heat insulating equipment is greater than that of the cooling tank or less than or equal to that of the quenching heating furnace. As the heat insulating equipment is additionally arranged between the quenching heating furnace and the cooling tank, the temperature of the tool joint discharged from the quenching heating furnace is substantially not changed and less contacts with air, so that oxidization on the surface of the tool joint is reduced, and thus the uniformity of section hardness and the stability of performances of the tool joint are improved.
Description
Technical field
The utility model relates to oil device apparatus and manufactures field, in particular, relates to a kind of equipment for Heating Processing of drill pipe sub.

The processing of the domestic current part drill pipe sub thermal treatment employing Yi Pusen of producer continuous heat treating furnace.Owing to adopting Open architecture in the middle of quenching heating furnace and cooling tank, there is certain drawback, drill pipe sub is directly exposed in air from quenching heating furnace is come out of the stove, drill pipe sub particularly peripheral surface temperature drop is very large, also caused the certain oxidation in drill pipe sub surface, cause drill pipe sub section hardness inhomogeneous, wherein oxide skin incorporates and in cooling tank, also affects the stable of performance of drill pipe connector.So be necessary, by improving equipment, to improve the homogeneity of drill pipe sub section hardness, improve the stability of performance of drill pipe connector simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of equipment for Heating Processing that improves the inhomogeneity drill pipe sub of drill rod hardness.
The purpose of this utility model is achieved through the following technical solutions:
A kind of equipment for Heating Processing of drill pipe sub, described equipment for Heating Processing comprises quenching heating furnace, the heat-preserving equipment being connected with quenching heating furnace, the cooling tank being connected with heat-preserving equipment, temperature in described heat-preserving equipment is greater than the temperature of cooling tank, is less than or equal to the temperature of quenching heating furnace.
Further, in described heat-preserving equipment, be provided with the adjustable heating unit of temperature.
Further, described heating unit comprises radiator element, and described radiator element is evenly arranged in the inner side of heat-preserving equipment, and radiator element arragement direction is parallel with drill pipe sub haul direction.
Further, described equipment for Heating Processing also comprises the transport tape that runs through described quenching heating furnace and heat-preserving equipment.
Further, described heat-preserving equipment outer wall wraps up Packed housing.
Further, in described heat-preserving equipment, be provided with the adjustable heating unit of temperature; Described heat-preserving equipment outer wall wraps up Packed housing; Described equipment for Heating Processing also comprises the transport tape that runs through described quenching heating furnace and heat-preserving equipment;
In described heat-preserving equipment, be provided with the adjustable heating unit of temperature; Described heating unit comprises radiator element, and described radiator element is evenly arranged in the inner side of heat-preserving equipment, and radiator element arragement direction is parallel with drill pipe sub haul direction.
The utility model is owing to having increased heat-preserving equipment between quenching heating furnace and cooling tank, after drill pipe sub is come out of the stove from quenching heating furnace, temperature is substantially constant, minimizing contacts with air, thereby reduce drill pipe sub surface oxidation, improve the stability of drill pipe sub section hardness homogeneity and performance.
