Revision Notes
This specification is based on the requirements of the State Planning Commission (86) Jizong No. 250 document, edited by our department, and specifically revised by the Wuhan Metallurgical Construction Research Institute in conjunction with the Ministry of Chemical Industry, the State Building Materials Industry Bureau and the relevant units of the China Nonferrous Metals Industry Corporation to revise the original "Industrial Furnace Masonry Engineering Construction and Acceptance Specification" GBJ211-80. During the revision process, the compilation team conducted extensive investigations and studies, carefully summarized the experience of my country's industrial furnace masonry engineering design, construction, scientific research and production use in recent years, and widely solicited opinions from relevant units across the country for many times. After repeated revisions, it was finally reviewed and finalized by our department in conjunction with relevant departments. This specification is divided into 18 chapters, of which the first, second, third, fourth, seventeen and eighteen chapters are general parts, including common provisions for various industrial furnace masonry projects, and the remaining chapters are special requirements for the listed professional furnace masonry projects. General industrial furnaces of various industrial sectors that are not included in special chapters in this specification can be constructed and accepted according to the general part of this specification. With the development of my country's four modernization construction projects, new technologies, new materials and new processes will continue to emerge. It is hoped that all units will carefully summarize their experience in the process of implementing this specification. If any modification or supplement is found, please send your opinions and relevant information to the "Industrial Furnace Masonry Project Construction and Acceptance Specification" Management Group of Wuhan Metallurgical Construction Research Institute (Qingshan District, Wuhan City) for reference in future revisions.

Chapter II Basic Provisions for Industrial Furnace Masonry
Section I Materials
(I) Acceptance, Storage and Transportation of Materials
Article 2.1.1 Refractory materials and products shall be accepted, stored and transported in accordance with the current relevant standards and technical conditions.
Refractory materials and products transported to the construction site shall have a quality certificate. Time-limited refractory materials shall indicate their validity period. Whether the brand, grade and brick number of refractory materials and products meet the standards, technical conditions and design requirements shall be checked or selected according to documents and appearance before construction. If necessary, they shall be inspected by the laboratory. Note: ① Materials that may deteriorate or must be inspected twice shall be inspected by the laboratory to prove that their quality indicators meet the design requirements before they can be used. ② When using refractory bricks recovered from furnace dismantling, the mud and slag on the bricks should be removed. Old bricks that have passed the inspection can be used to build secondary parts of industrial furnaces.
Article 2.1.2 The refractory material warehouse and the transportation road leading to the warehouse should be built before the refractory materials are transported to the site. Article 2.1.3 The refractory materials in the construction site warehouse should be placed according to the brand, grade, brick number and masonry sequence, and marked. Refractory products should be handled with care when transporting and loading and unloading. Article 2.1.4 For large industrial furnace masonry projects, refractory products should be transported in containers.
Article 2.1.5 When transporting and storing refractory materials, moisture should be prevented. Silica bricks, corundum bricks, magnesia products, carbon products, insulating refractory bricks, insulating products, etc. and high-alumina bricks and clay bricks used in important parts should be stored in covered warehouses.
Refractory materials that are easily deteriorated by moisture (such as magnesium products, etc.) must not be exposed to moisture. Article 2.1.6 Refractory mud, powder, aggregate, binder, ramming material, plastic, spray coating, castable and refractory fiber must be stored separately in warehouses that can prevent moisture and dirt, and must not be mixed. Refractory materials with antifreeze requirements should take antifreeze measures. (I) Mud
Article 2.1.7 The refractoriness and chemical composition of the mud used for masonry refractory products should be compatible with the refractoriness and chemical composition of the refractory products used. The type, brand and other performance indicators of the mud should be selected by the designer based on the temperature and operating conditions of the furnace. The types and compositions of mud generally used for refractory masonry are shown in Appendix 1. Article 2.1.8 Before masonry of industrial furnace, the consistency and water addition of mud shall be determined by test according to the masonry type, and the masonry performance of mud (mainly bonding time) shall be checked to see whether it can meet the masonry requirements.
The bonding time of mud shall be determined by the size of the external dimensions of refractory products, and it is preferably 1 to 1.5 minutes.
Article 2.1.9 The consistency of different types of mud and the masonry types to which they are applicable may be adopted according to Table 2.1.9.
