The invention relates to a bracket structure for a chute area of a dry quenching furnace. The bracket structure is formed by building a plurality of layers of bracket bricks; and a plurality of supporting pieces are arranged between every two adjacent layers of bracket bricks, the supporting pieces are hard supporting pieces, the thickness of the supporting pieces is the same as that of mortar joints, the top faces of the supporting pieces make direct contact with the upper layer of bracket bricks, and the bottom faces of the supporting pieces make direct contact with the lower layer of bracket bricks. The supporting pieces are placed in the refractory mortar joints between the bracket brick layers, so that the problems of sinking of the annular air duct and cracking of the chute partition wall caused by deformation of the bracket mortar joints and inaccurate bracket elevation control are effectively prevented, the masonry quality of the dry quenching furnace is improved, and the service life of the dry quenching furnace is prolonged.

The present invention discloses an integrated high-performance lining brick for a converter and a preparation method thereof, which belongs to the technical field of refractory materials for steel smelting converters, and comprises a brick body, wherein the brick body comprises a permanent layer of magnesium bricks and a working layer of magnesium carbon bricks, wherein the permanent layer of magnesium bricks and the working layer of magnesium carbon bricks are connected by a slot structure. The preparation method comprises the following steps: weighing each raw material; mixing and secondary molding operation; drying the integrated lining brick blank of the working layer of magnesium carbon bricks and the permanent layer of magnesium bricks to obtain an integrated high-performance lining brick for the converter. The integrated high-performance lining brick of the present invention can simplify the masonry process, greatly shorten the masonry time, complete the masonry task within the specified time, meet the requirements of the steel plant, and improve the integrity of the refractory material of the converter lining. The present invention has a simple production process, no high-temperature firing process, gets rid of the dependence on high-temperature tunnel kilns, etc., reduces manufacturing costs, saves resources, responds to the national call for energy conservation and emission reduction, and is beneficial to environmental protection.

The present invention relates to a corbel structure of a chute area of ​​a dry quenching coke oven, wherein the corbel structure is constructed by masonry of multiple layers of corbel bricks; a plurality of support members are arranged between two adjacent layers of corbel bricks, wherein the support members are hard support members, the thickness of which is the same as the thickness of the mortar joints, the top surface of the support members is in direct contact with the upper layer of corbel bricks, and the bottom surface of the support members is in direct contact with the lower layer of corbel bricks. The present invention effectively prevents the sinking of an annular air duct and the cracking of a chute partition wall caused by deformation of the corbel mortar joints and inaccurate control of the corbel elevation, thereby improving the masonry quality and service life of the dry quenching coke oven.

The utility model relates to a horizontal masonry mortar laying device which comprises two longitudinal side face positioning rods, two longitudinal coping positioning rods and two transverse connecting rods, and the two longitudinal side face positioning rods are arranged side by side in the left-right direction and in the front-back direction. The two longitudinal coping positioning rods are in one-to-one correspondence with the two longitudinal side surface positioning rods, the longitudinal coping positioning rods are arranged on the upper sides of the corresponding longitudinal side surface positioning rods and are in the front-back direction, and the tops of the longitudinal side surface positioning rods are detachably connected with the outer side parts of the longitudinal coping positioning rods; the two transverse connecting rods are arranged on the upper sides of the two longitudinal side face positioning rods side by side front and back, the transverse connecting rods are in the left-right direction, and the transverse connecting rods are detachably connected with the two longitudinal side face positioning rods. According to the horizontal mortar laying device for the masonry, a worker can conveniently conduct construction on the upper portion of the constructed masonry so as to form horizontal mortar joints which are filled compactly and uniform in thickness, the construction quality of the masonry mortar joints can be better guaranteed, and the appearance of the masonry mortar joints of a masonry wall and the masonry quality can be improved.
