Embodiment 1

[0032] Example 1 1. A special material with high thermal shock resistance, refractory and heat insulation interlocking dry code (round convex dry code brick).

[0033] refer to Figure 1-Figure 3 , this round convex dry code brick is a rectangular brick body. On the top of the brick body, there is a spherical crown card convex matrix a, and under the brick body, there is a concave cavity b matrix. The concave cavity matrix is ​​connected with the other brick body Ball crown card convex a matrix concave-convex card sleeve fit.

Embodiment 2

[0034] Example 2 1. A special material with high thermal shock resistance, refractory and heat insulation interlocking dry code (square convex dry code brick).

[0035] refer to Figure 4-Figure 6 , this square convex dry code brick is a rectangular brick body. On the upper side of the brick body, there is a square-shaped convex matrix a, and on the lower side of the brick body, there is a concave cavity b matrix. The concave cavity matrix is ​​connected with another brick. The square platform of the body is fitted with a matrix concave-convex ferrule.

Embodiment 3

[0036] Example 3 1. A special material with high thermal shock resistance, refractory heat insulation interlocking dry code, its structure is the same as that of embodiment 1 or embodiment 2, and the raw and auxiliary materials prepared by it include the following materials by weight: aggregate 40wt%, composite matrix 60wt% of raw materials, based on 100% of aggregate and composite matrix materials, plus: 12wt% of waste burnt additives; 10wt% of crystal nucleating agents, 3.1wt% of binders, 4.5wt% of plasticizers, Water is the 16-18wt% of material sum, wherein:

[0037] (A) Aggregate, selected from cordierite-mullite, cordierite, high alumina and clay waste refractory brick clinker, the waste refractory brick clinker is classified, selected, impurity removed, crushed, screened and classified, It is prepared by removing iron, and the particle size passes through a 80-mesh sieve. High-alumina waste refractory brick clinker accounts for 40wt% of the aggregate; clay waste refrac...

Abstract

The invention relates to a high-thermal-shock-resistant fire-resistant and thermal-insulating interlocking dry-code special material prepared by utilizing waste firebricks and a method thereof. The high-thermal-shock-resistant fire-resistant and thermal-insulating interlocking dry-code special material comprises the following materials: a bone material, a composite matrix material, a waste born-out additive, a nucleating agent, an adhesive, a plastifying agent and water; the interlocking dry-code special material is a rectangular brick on which is provided with a clamping convex matrix, and a concave cavity matrix is arranged below the brick and is in convex-concave match with a clamping convex matrix of another brick. When in masonry, the bricks are not adhered with fireproof slurry, the whole structure is firm, and the problem existing in a traditional kiln car base can be fully solved. Meanwhile, the invention is also suitable for use by a preheating zone and a cooling zone of a tunnel kiln, can greatly lighten the weight of a kiln car, prevents heat loss, reduce energy consumption, prolongs the service life for durable use, hardly needs repairing and is not only suitable for a newly-built kiln, but also suitable for modifying an old kiln. The invention brings the social benefits of comprehensively utilizing waste resources, improving the ecological environment, saving energy and reducing consumption for the society.

Description

Technical field [0001] The present invention involves a high -heat shock resistance and heat -resistant interoperability dry code special material and its preparation methods.In particular, a high -heat shock -resistant fire -resistant interoperability dry code special material and methods are prepared using waste fire -resistant bricks. Background technique [0002] The current kiln car base is generally adopted with flat -plate heavy bricks and lightweight bricks as a siege structure. It not only consumes large calories, but also has serious problems such as loosening, cracking, and peeling.The sealing of the kiln wall is poor. The heat is easy to pass to the bottom of the kiln car. It not only wastes the heat energy, but also causes various defects such as the deformation of the steel structure of the kiln car and the damage of the bearings. Invention content [0003] The purpose of the present invention is to provide a special material and method of high anti -heat shock res...
