1 Transportation of refractory materials and refractory products
1.1 All refractory materials and refractory products for furnace building must have a factory certificate of conformity to the technical conditions of this design. One month before the construction of the furnace, a copy of all the factory test reports of refractory materials should be copied and submitted to the metallurgical furnace major of this design institute or the construction site working group of this design institute. Before leaving the factory, the product should be accompanied by a quality certificate, indicating the product name, brand number, inspection result, and shipping list (brick number, quantity, shipping date, carriage number). Refractory materials without product qualification certificates are strictly prohibited from shipment and use.
1.2 The shipping tools (trains, cars, ships, etc.) of refractory materials and refractory products must be cleaned before shipment, and must not be contaminated with oil or other impurities. There must be measures to prevent direct contact with rain and snow during transportation to ensure that the refractory materials are not exposed to rain and water.
1.3 All kinds of clay special-shaped bricks, high-alumina special-shaped bricks, light-weight special-shaped bricks, and light-weight standard bricks should be packed and transported in containers or other sturdy packaging products; standard and ordinary clay bricks can be wrapped with straw rope transport. Care should be taken to avoid damaging the edges and corners of various refractory products during transportation.
1.4 When loading, unloading and stacking various refractory materials, they must be handled lightly and arranged closely to avoid collision damage. Products of different types and different brick numbers shall be clearly marked and shall not be mixed. It is strictly forbidden to toss, roll down, pile up and dump all kinds of refractory products in barbaric handling and management.
1.5 The tolerance ratio of all kinds of products, such as positive tolerance and negative tolerance, should be reflected in the order contract, and the goods should be delivered according to the design requirements. At the same time, they should be packed separately according to the design requirements Value.
1.6 Aluminum silicate refractory fiber products should be packed and transported in a carton with plastic bags inside, and the name, material and specifications should be marked outside the carton.
1.7 Refractory mud, ash, castables and other bulk refractory materials should be packed and transported in woven bags or thick paper bags lined with thick plastic bags. The name, brand, specifications and production date of the materials should be indicated on the outside of the bags To be clear, bulk transportation is strictly prohibited.
2 Guarantee of refractory materials and refractory products
2.1 After various types of refractory materials and refractory products are delivered to the site, they should be stacked separately according to different categories, different models and different tolerances, and obvious signs should be inserted.
2.2 The warehouse where refractory materials and refractory products are stacked should be cleaned up. Sand, lime, cement, clay, coal, grease and other debris should not be piled up in the warehouse. No rain or snow leakage and underground and surface water infiltration are allowed in the warehouse.
2.3 Standard, general bricks, special-shaped bricks, lightweight bricks, refractory fiber products, asbestos products; and powder materials such as refractory mud, ash, castables, etc., must be stacked in the warehouse in order according to brand, grade, brick number and masonry . If limited by the area of the warehouse, standard clay bricks can be stacked in the open field, but there must be canvas or temporary roof to cover rain and snow.
2.4 Before the refractory materials and refractory products are transported to the warehouse, a detailed visual inspection shall be carried out. If necessary, the physical and chemical indicators shall be re-examined with the relevant personnel. Contact the relevant refractory manufacturer to make up for the shortage as soon as possible.
