Problems solved by technology

[0002] Unshaped refractories are widely used to prepare the inner lining of kilns, which play the role of fire resistance, heat insulation, and heat preservation. In addition, due to the temperature change of the kiln, the lining will crack and fall off
[0003] Ceramics have good refractory, wear-resistant and corrosion-resistant properties, but due to the difference in expansion coefficient between them and refractory materials, they are easy to fall off from refractory materials

Embodiment 1

[0025] Embodiment 1: Ceramics and self-flowing castables are constructed using formwork, and the steps are as follows:

[0026] 1) Weld the anchor hook or metal mesh on the base steel plate or water wall;

[0027] 2) Install the ceramic assembly on the template;

[0028] 3) Install the formwork with the installed ceramic assembly in the kiln;

[0029] 4) Fill the self-flowing castable between the matrix and the template, so that the inserts of the ceramic assembly are embedded in it;

[0030] 5) Carry out maintenance and oven for refractory materials.

Embodiment 2

[0031] Example 2: Ceramics and self-flowing castables are constructed without templates, and the steps are as follows:

[0032] 1) Weld the anchor hook or metal mesh on the base steel plate or water wall;

[0033] 2) Pour the self-flowing castable directly into the filling part;

[0034] 3) Insert the ceramic assembly insert into the unsolidified self-flowing castable;

[0035] 4) Carry out maintenance and oven for refractory materials.

Embodiment 3

[0036] Embodiment 3: pottery and spray paint adopt formwork construction, and its steps are as follows:

[0037] 1) Weld the anchor hook or metal mesh on the base steel plate or water wall;

[0038] 2) Install the ceramic assembly on the template;

[0039] 3) Install the formwork with the installed ceramic assembly in the kiln;

[0040] 4) Spray the spray paint between the substrate and the template, so that the inserts of the ceramic assembly are embedded in it;

[0041] 5) Carry out maintenance and oven for refractory materials.

Abstract

The invention relates to a construction technology for preparing a kiln lining by compounding ceramics and unshaped refractory materials and belongs to a construction technology. The construction technology mainly solves the problem of short service life of an existing unshaped refractory material of a kiln lining. The technical scheme includes that a ceramic composite is arranged on a mold plate or a ceramic composite inserting piece is inserted into the unset unshaped refractory materials during construction, so that the unshaped refractory materials is mechanically connected with the ceramics. The advantages of the ceramics and the unshaped refractory materials are combined, and the shortcomings of the ceramics and the unshaped refractory materials are overcome, so that service life of the kiln lining is prolonged.

Description

technical field [0001] The invention belongs to a construction technology, in particular to a construction technology for preparing a kiln lining by compounding ceramics and unshaped refractory materials. Background technique [0002] Unshaped refractories are widely used to prepare the inner lining of kilns, which play the role of fire resistance, heat insulation, and heat preservation. In addition, due to changes in the temperature of the kiln, the lining will crack and fall off. [0003] Ceramics have good fire resistance, wear resistance, and corrosion resistance, but due to the difference in expansion coefficient between them and refractory materials, they are easy to fall off from refractory materials. Contents of the invention [0004] The purpose of the present invention is to overcome the problem of shedding of ceramics and unshaped refractory materials, and provide a construction technology for preparing furnace linings by combining ceramics and unshaped refract...
