Abstract
The utility model discloses a blast furnace cross temperature measuring device. A high-temperature facing air flow surface is formed by an oval steel pipe welded below a cross temperature measuring device rod part and a U-shaped steel pipe; air flow flows inside the steel pipes with no dead area; the high-temperature facing air flow surface is enabled to weather hot flow impact of high-temperature coal gas flow inside a furnace; and the oval steel pipe and the U-shaped steel pipe exert protection function on welding bead on the back portion, thereby the blast furnace cross temperature measuring device overcomes the shortcoming that a welding bead of an existing similar product is easy to be cracked after being heated. A protective plate with wear resistance and temperature insulation performance added on the outer lateral wall of the rod part exerts heat insulating function on the rod part and lowers the temperature of the lateral wall of the rod part, thereby enabling the integral service life of the cross temperature measuring device to be prolonged.
Description
Technical field
The utility model belongs to technical field of metallurgy industry, disclosed blast furnace cross temperature measuring equipment, the technical scope that belongs to the design of blast furnace technology equipment and make.
Background technology
At present, the cross temperature measurer that domestic large blast furnace uses is based on patent 200520033132.0 determined wedge shape cross temperature measurers.This cross temperature measurer is welded by the steel plate of several pieces strips, its inner one to two road cooling-water duct that forms.The High Temperature Gas stream interface of meeting of this cross temperature measurer is its wedge-like portion housing.This partial shell is to be formed on the cross temperature measurer web by the welding of the steel plate of two strips.For this reason, there are two perforation weld seams along its length at least in the bottom of wedge shape.This weld seam becomes the weak link of meeting the High Temperature Gas stream interface.Because the mezzanine space in the wedge shape is exactly the cooling channel that is sharp-pointed horn shape, there is the dead band in water coolant when flowing through therein, bad phenomenon can occur cooling off.Therefore, when this cross temperature measurer uses on large blast furnace, mainly be because meet after the High Temperature Gas stream interface bears high temperature, cause above-mentioned two to connect weld seams and at first ftracture and leak because cooling is bad, thereby shortened the work-ing life of cross temperature measurer greatly.

The purpose of this utility model is: at the above-mentioned defective of cross temperature measurer, utility model is a kind of to have good cooling performance, water stream channel does not have the cooling dead band, meets the High Temperature Gas stream interface and do not have the cross temperature measurer that connects weld seam.
Realize that the above-mentioned purpose technical scheme is: this cross temperature measurer mainly is made of an oval steel pipe, U-shaped steel pipe, protecting sheet, thermopair and a sleeve pipe thereof and cross temperature measurer rod member, it is characterized in that: rod member is a welding assembly, have and place thermopair and telescopic mezzanine space thereof, the mezzanine space both sides are provided with but two water channels of current warp of cooling; In the rod member bottom, stretched out four limits longitudinally respectively, wherein: the edge length direction that constitutes two middle pectoral plates of rod member mezzanine space is welded on the oval steel pipe, and the limit and the U-shaped steel pipe of rod member outside housing weld along its length; The center of U-shaped steel pipe is than the height of center of oval steel pipe, and oval steel pipe is sandwiched in the long steel pipe of U-shaped, and both tube walls keep in touch, and roughly forms the cross temperature measurer bottom of similar " U " shape, and what constituted cross temperature measurer meets the High Temperature Gas stream interface; On oval steel pipe, the temperature measurement location by processing requirement has a plurality of holes of passing oval cross-section, and heat supply galvanic couple and sleeve pipe thereof pass the usefulness of oval steel pipe, and welded seal is adopted in its sleeve pipe and oval steel pipe contact position; At the cross temperature measurer head, two water channels in oval steel pipe and the rod member are connected by one section short steel pipes, thereby constitute a water stream channel independently jointly, from oval steel pipe water inlet, by two passage water outlets of rod member; The U-shaped steel pipe is an independently water stream channel of another road, from a water inlet other end water outlet; Outer shell body wall at rod member is provided with protecting sheet wear-resisting, thermal insulation, can adopt Bolt Connection or riveted joint between protecting sheet and the rod member.
Rod member described in above-mentioned cross temperature measurer outside housing is a U-shaped strip steel plate with U-shaped steel pipe medullary ray equivalent length and shape.
Oval steel pipe described in the above-mentioned cross temperature measurer can be two tight welderings steel pipes together.The edge length direction that constitutes two middle pectoral plates of rod member mezzanine space is welded on the steel pipe respectively; Between two steel pipes, the temperature measurement location by processing requirement has a plurality of holes of passing two steel pipes on its osculatory, and heat supply galvanic couple and sleeve pipe thereof pass the usefulness of two steel pipes, and welded seal is adopted in its sleeve pipe and two steel pipe contact positions; At the cross temperature measurer head, two water channels in these two steel pipes and the rod member are to be connected by one section short steel pipes respectively, thereby constitute a water stream channel independently jointly; Cooling-water flowing after rod member opposite side water channel is turned back, flows out by another root steel pipe by the flow through water channel of rod member one side of steel pipe wherein again.
Oval steel pipe described in the above-mentioned cross temperature measurer and U-shaped steel pipe can also be copper pipes; Rod member can be container steel, boiler steel or stainless steel.
The beneficial effects of the utility model are embodied in: cross temperature measurer meet the High Temperature Gas stream interface, it is the face of similar " U " shape of constituting by an oval steel pipe and U-shaped steel pipe, current flow in steel pipe, the dead band can not appear, improved the cooling performance of cross temperature measurer, made and meet the hot-fluid impact that the High Temperature Gas stream interface can stand furnace high-temperature coal gas stream; Welding position between oval steel pipe and U-shaped steel pipe and rod member, at the back side of meeting the High Temperature Gas stream interface, its weld seam directly is not subjected to the thermal shocking of high temperature gas flow, has therefore avoided the weld seam cracking that is heated, and has prolonged rod member work-ing life; In addition; the protecting sheet of wear-resisting, the thermal insulation that is provided with at the outer side wall of rod member can play heat-blocking action to the top of cross temperature measurer rod member, has reduced the temperature of rod member sidewall; improved rod member sidewall fastness to wear simultaneously, the whole service life of cross temperature measurer is improved.
