Abstract
The utility model relates to an apparatus detecting the gas temperature in the blast furnace, in particular to a detector for blast furnace top gas temperature. The technical proposal is that the detector is composed of a protection plate (1), a ribbed slab (2), a transverse plate (5), a lateral plate (6), and a thermocouple (8). The lateral plate (6) is delimited to form the working cavity of the apparatus, and the transverse plate (5) lies in the working cavity formed by the lateral plate (6). The transverse plate divides the working cavity into two parts, and a working cavity of recirculated water (4) is formed by the upper side of the transverse plate and the lateral plate. The outside of the lateral plate is fixed with the ribbed slab (2), and one side of the working cavity of recirculated water subjected to the wash of the materials is provided with the protection plate (1). The protection plate and the ribbed slab is in dead joint, and the working cavity of thermocouple (7) is formed by the lower side of the transverse plate and the lateral plate. The thermocouple (8) is arranged in the working cavity of thermocouple (7). Because one side of the working cavity of recirculated water subjected to the wash of the materials is provided with the protection plate, the working cavity of recirculated water is made to be away from the wash of the materials, and the wash of the materials resistant capability of the working cavity of recirculated water is improved. The working cavity of recirculated water is without deformation, so the useful life of the detector for blast furnace top gas temperature is prolonged.

Affiliated technical field:
The utility model relates to a kind of device of surveying gas temperature in the State of Blast Furnace, particularly is arranged on the gas temperature sniffer of blast furnace furnace roof.
Background technology:
At present, in blast furnace smelting process, people need survey gas temperature in the State of Blast Furnace, for blast furnace process provides technical parameter, four temperature probes of the general online use of top gas temperature detection device, be cruciform and be installed on roof material distributing chute below, existing gas temperature sniffer material of main part all adopts the 1Cr18Ni9Ti steel plate to be welded into working chamber, length approximates the radius of blast furnace chamber, the working chamber epicoele separates with the 1Cr18Ni9Ti steel plate, end UNICOM is the recirculated cooling water working chamber, at cavity of resorption, after installing steel pipe according to point for measuring temperature, pouring clay matter and high alumina refractory casting material insert thermopair in the steel pipe, and this device adopts flange to be connected and fixed on furnace roof inspecting hole flange.It is the recirculated cooling water working chamber that existing gas temperature sniffer is subjected to material to wash away position easy to wear, directly influence the withstand voltage properties of recirculated cooling water working chamber behind the abrasion deformation, cause the cooling failure that circulates, and then aggravate the distortion of whole device, cause online equipment life cycle short, change frequent.Because material of main part adopts 1Cr18Ni9Ti, belong to austenitic stainless steel, the austenitic stainless steel coefficient of heat conductivity is little, fusing point is low, linear expansion coefficient is big, therefore, and under identical welding conditions, the zone that is heated to more than 600 ℃ is big, the weld metal high-temperature residence time is long, forms thick as-cast structure easily, and produces bigger stress and distortion, the existence of unrelieved stress easily produces sweating heat stress cracking and stress corrosion crack, when welding material or selection of Welding are incorrect, defectives such as intercrystalline corrosion or fire check can appear, therefore, the making and the renovation technique difficulty of equipment are big in production practices are used, and are unfavorable for the reduction of production cost.
The utility model content:
The utility model purpose provides a kind of top gas temperature detection device, improves whole device and resists the ability that material washes away, and prolongs the serviceable life of sniffer, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the top gas temperature detection device is by protective shield, gusset, transverse slat, side plate and thermopair are formed, side plate surrounds the working chamber of this device, transverse slat is positioned in the middle of the working chamber that side plate surrounds, transverse slat is divided into two parts with working chamber, what surround with side plate above the transverse slat is the recirculated water working chamber, the fixed outside gusset of side plate, be subjected to the side that material washes away at the recirculated water working chamber protective shield is set, protective shield is fixedlyed connected with gusset, what surround with side plate below the transverse slat is the thermopair working chamber, and temperature thermocouple is arranged in this working chamber.
In order to strengthen the intensity of protective shield, the utility model also is provided with riser, and riser is fixed on the interior transverse slat of recirculated water working chamber, and passes from the recirculated water working chamber, and the external part of riser is fixedlyed connected with protective shield, improves the intensity of protective shield.
Adopt the utility model; owing to be subjected to the side that material washes away protective shield is set at the recirculated water working chamber; make the recirculated water working chamber away from material wash away; improve the anti-material scouring capability of recirculated water working chamber; protection recirculated water working chamber is indeformable; prolonged top gas temperature detection device serviceable life; in order further to improve the serviceable life of gas temperature sniffer; be subjected to material to wash away workplace built-up welding heat resistant and wear resistant alloy-layer easy to wear at the utility model; because the working temperature of top gas temperature detection device is 500 ℃～900 ℃; this temperature is in the serviceability temperature scope of Q235 material; therefore top gas temperature detection device material of main part adopts the Q235 steel plate; adopt this cheap material can reduce manufacturing cost; body adopts the Q235 material simultaneously; weldability is fine, has reduced the making and the renovation technique difficulty of spare part.
Characteristics such as the utlity model has anti-material scouring capability rational in infrastructure, easy to install, as to improve the recirculated water working chamber, increase the service life.
