The utility model content
The utility model is at the deficiency that above-mentioned prior art exists, and a kind of simple in structure, reasonable in design, spud leg main shipboard tube heating and heat-insulating device that heating efficiency is high is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of spud leg main shipboard tube heating and heat-insulating device, comprise body of heater, it is characterized in that, described body of heater comprises process furnace base and the process furnace insulation cover that is sleeved on the described process furnace base, equidistantly be provided with heating piece on the described process furnace base, be provided with between the described heating piece for the support platform that supports main shipboard tube.
Further, the periphery of described process furnace base is provided with supporting baffle, and the bottom of described process furnace insulation cover is supported on the described supporting baffle, thereby realizes the split-type structural of process furnace insulation cover and process furnace base.
Further, be respectively equipped with hanger on described process furnace insulation cover and the process furnace base.
Further, also comprise for the Controlling System of controlling furnace body temperature.
The beneficial effects of the utility model are: process furnace insulation cover and process furnace base flexibly connect, by hanger the process furnace insulation cover is taken off, workpiece to be heated is placed on the support platform on the process furnace base, then the process furnace insulation cover is put back to, because heat-processed is to carry out in the enclosed space in the body of heater, operator directly do not contact with product and heating piece, so security is higher; Described heating piece is arranged on the process furnace base, and heat makes heating and temperature control even by being fully utilized from last dissipate heat down during heating, does not heat the blind area, realizes that welding stress evenly discharges, and avoids welding flaw; Can monitor temperature in the body of heater by Controlling System in addition, thereby realize that temperature is adjustable.The utility model not only can also carry out weld preheating to associated component to the main shipboard tube postweld heat preservation, compares with existing heat preserving method, and heating efficiency is greatly improved.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described process furnace insulation cover and process furnace base all are made up of iron sheet and the lagging material that is wrapped in the middle of the iron sheet.
Further, described support platform is joist steel.
Adopt the beneficial effect of above-mentioned further scheme to be, further the enclosed space to process furnace insulation cover and the formation of process furnace base is incubated, and reduces thermal losses, and the support platform assurance workpiece main shipboard tube of joist steel is fully accepted the heat from heating piece.
