Embodiment 1

[0039] figure 1 A schematic structural view of the mandrel insulation device provided in Embodiment 1 of the present invention, such as figure 1 As shown, the mandrel insulation device provided by the embodiment of the first aspect of the present invention includes a swing beam 4 and a closed furnace body 1, the swing beam 4 is penetrated in the furnace body 1, and on the swing beam 4 A mandrel 5 is provided, and a burner 3 is provided on the furnace body 1 corresponding to the mandrel 5, and the burner 3 is provided with flue gas, and the furnace body 1 is provided with a flue gas for exhausting the flue gas. Road 2.

[0040] In the mandrel insulation device provided by the present invention, the furnace body 1 is provided with a burner 3 corresponding to the mandrel 5, the burner 3 is provided with flue gas, and the furnace body 1 is provided with a The flue 2 of the gas; through the flue gas heating, the local high temperature of the flame is avoided, and the mandrel 5 is...

Embodiment 2

[0056] In order to protect the environment, in any of the above technical solutions, further, the flue 2 is connected to an induced draft fan, and the flue gas is exhausted to the outside through the induced draft fan. Prevent the environmental pollution of the processing site from being large and causing great harm to personnel. The rest are the same as the first embodiment, and will not be repeated here.

[0057] In the mandrel heat preservation device provided by the present invention, the mandrel 5 is uniformly heated in a relatively closed space of the furnace body 1, and the heat uniformity effect is optimal. At the same time, with the control of the opening degree of the electromagnetic valve in the burner 3 and the temperature of the flue gas, the temperature can be adjusted according to the actual situation of the mandrel 5 to the greatest extent, so as to ensure the uniform heating effect of the mandrel 5 in the furnace body 1 . The movement of the mandrel 5 on the ...

Abstract

The invention provides a mandrel heat preservation device and a mandrel temperature adjustment system and relates to the technical field of seamless steel tubes. The mandrel heat preservation device comprises a swing beam and a sealed furnace body, and the swing beam is arranged in the furnace body in a penetrating manner. The swing beam is provided with mandrels, the furnace body is provided withburners corresponding to the mandrels, smoke is introduced into the burners, and the furnace body is provided with a flue for discharging the smoke. According to the mandrel heat preservation device,heating is performed through the smoke, and the condition of a local high-temperature of a flame is avoided; and the mandrels are located in the sealed furnace body, heating uniformity can be guaranteed, the smoke can be discharged through the flue and cannot pollute air, and the mandrel heat preservation device and the mandrel temperature adjustment system have the advantages of being uniform inheating, environmentally friendly and the like.

Description

technical field [0001] The invention relates to the technical field of seamless steel pipes, in particular to a mandrel heat preservation device and a mandrel temperature regulating system. Background technique [0002] The mandrel is a part of the mold used to form the profile surface in the compact or sintered body in the pressing direction, mainly the inner mold of the seamless steel pipe. [0003] Existing mandrel heat preservation device The mandrel heat preservation device adopts an open heating method, the grid plate is located on the top of the mandrel, and the flame is heated by the flame injection nozzle and the grid plate to evenly distribute the flame. To ensure that the mandrel will not be locally high temperature. [0004] However, the heating capacity is greatly reduced through the heating of the grid plate. If the heating capacity is large, the mandrel may have a local high temperature, and the heating capacity is small, so the heating effect cannot be achie...
