GB/T 45132000
This standard is a comprehensive revision of the classification of 4 shaped refractory materials (tight insulation) in GB/T 51319. This revision has made major revisions to the following clauses: 1. The requirements for the refractoriness of amorphous refractory materials in the original standard + the special heat transfer rate of refractory materials are listed separately as ·· clauses, and refractory ceramic castables are subdivided into refractory castables, low cement castables, ultra-low cement castables and water-free castables. The mineral composition is added to the chemical composition table! 2. The first check "technical fall" of the original standard is cancelled: 3. The classification is divided into first-level classification and first-level classification. This standard shall be implemented from the date of implementation, and shall replace B/T4513-954 unshaped refractory materials (caused by capital and weak heat: classification. This standard is proposed by the State Administration of Industry and Information Technology of the People's Republic of China. This standard is submitted by the State Refractory Industry Bureau.

This standard adopts the following definitions.
2.1 Small shaped refractory materials are made of bulk refractory materials, fine powders and binders. If necessary, additives can be added. 2.2 Combination forms
2-2. Reduction of the composition
Ceramic band
High tear, medium 2.2.2 Water-repellent bond formed by sintering: a form of bond in which the non-material and quality are connected together. 2.2.2 Water-repellent bond: hardened by hydration and condensation under room temperature. 2-2-3 Chemical bond: chemical bond (especially organic, inorganic-organic bond) is produced by chemical reaction, not hydration reaction) at room temperature or incubation.
2.2. Organic bonding
Hardening in room temperature or at high temperatures 7. Due to the use of organic substances, hardening occurs: Method: There are several ways to combine a binder with a ruler, and the properties of the binder are determined according to the chemical composition of the main application. 2.3 The whole structure of the material
2.3.1 Resistant to ramming material
Used in the amorphous material of the construction method (robot 2 grams) 2.3-2 Plastic p:agti (moldable) meteriel has high flexibility and is delivered in soft, block, sheet and other forms. After construction, the amorphous material is hardened. 2.3.3 Resistant to k The refractories are mainly delivered in ten ways, such as water-soluble solids mixed with filter media, and can be prepared into hardened parts. a) Medium cement refractory castables (Mcc): hydraulically hardened refractory castables containing cement, with an oxide content greater than 3.5%. h) Low water settling refractory castables (LCc): refractory filter media containing 1.0% to 2.5% calcium carbonate. c) Ultra low cement refractory castables (LC): refractory castables with a calcium carbonate content of 0.% to 1.%.

a) Cement-free fire varnish material (Ncc) Calcium yellowing compound (calcium nitrate) 2-density refractory injection material. 2.34 Fire pressure injection
When using, add water to reduce liquid mixture to form a precious state or slurry, and use pressure treatment to construct non-shaped refractory materials. 2.3.5 Refractory spraying material gLnning mterit1 Indefinite refractory material constructed by mechanical mass jet. 2.4 Refractory building link material
This material can be applied by a spatula or similar workers, or by a "submerged cake" or cold me war This material can be divided into three categories 2.4.1 Water-based pre-fire slurry refrneturywrlarofbytirtulicseting fiber refractory aggregate, refractory materials with cement as binder mixed materials. 2.4.2
Retractory morta of heat setting slurry is a mixture of fine refractory aggregate, refractory powder and phosphate refractory acid salt. 2.4.3 Gas hardening slurry is a mixture of fine refractory aggregate, refractory ageing material and gaseous binder such as silicate. 2.5 Refractory coating
It is a mixture of refractory, refractory ageing material and binder. It is applied by hand or machine brushing or smearing. 3 Classification
3.1 Classification principle
The classification that must be adopted is the first-level classification, and the classification that can be selected is the second-level classification. The first-level classification code adopts the phonetic alphabet, and the second-level classification code adopts the combination of chemical symbols and numbers and their special letters. 3.2-Under the provisions of classification
3.2.1 Unshaped refractory materials are divided into two categories: balanced materials and insulation materials. The porosity of the insulation material particles is not less than 45%, expressed as mother G:
3.2.2 Classification based on the main chemical composition (mineral composition) of the entire mixture, and (or) the aggregate properties that determine the durability of the mixture (for example, ferrite, chromium, etc.), see Table 1, Table 1 Main chemical composition, code group reduction classification
