How are refractories transported and stored?
1 Transport of refractory materials and refractory products
1.1 All refractory materials and refractory products used in furnace construction must have a factory qualification certificate that meets the technical conditions of this design. One month before the construction of the furnace, the factory test report of all refractory materials shall be copied and submitted to the metallurgical furnace specialty of the design Institute or the construction site working group of the Design Institute. Products before leaving the factory should be accompanied by a quality certificate, indicating the product name, brand, inspection results, and attached to the delivery list (brick number, quantity and delivery date, car number). The shipment and use of refractory materials without product qualification certificate are strictly prohibited.
1.2 The means of transporting refractory materials and refractory products (trains, automobiles, ships, etc.) must be cleaned before loading, and there must be no pollution such as oil or other impurities. During the transportation process, there must be anti-rain and snow measures to ensure that the refractory is not soaked by rain.
1.3 All kinds of clay shaped bricks, high aluminum shaped bricks, light shaped bricks, light standard bricks, should be packed in containers or other strong packaging after transportation; Standard type, general type clay brick can be wrapped with straw rope after transportation. In transportation, attention should be paid to avoid damaging the edges and corners of all kinds of refractory products.
1.4 When loading and unloading and placing all kinds of refractory materials, they must be handled lightly and arranged closely to avoid collision damage. Products of different types and different brick sizes should be marked clearly and should not be mixed. It is strictly prohibited to carry out rough handling and management of all kinds of refractory products, such as throwing, rolling, piling, etc.
1.5 For all kinds of products such as positive tolerance and negative tolerance, the tolerance ratio shall be reflected in the order contract, and the goods shall be delivered according to the proportion required by the design. At the same time, the products shall be packed separately according to the proportion required by the design, and the positive and negative tolerance values shall be indicated on the outer surface of the packing box.
1.6 Aluminum silicate refractory fiber products should be packed in cartons with plastic bags, and the name, material and specifications should be indicated on the carton.
1.7 Refractory mud, ash, castable and other loose refractory materials should be packed and transported in woven bags or thick paper bags lined with thick plastic bags. The name, grade, specification and production date of the materials should be indicated outside the bags, and the marks should be clear. Loose transportation is strictly prohibited.
2 Refractory materials and refractory products
2.1 All kinds of refractory materials and refractory products should be stacked according to different categories, different models and different tolerances after arrival at the site, and obvious signs should be placed.
2.2 The warehouse where refractory materials and refractory products are stacked shall be cleaned. Sand, lime, cement, clay, coal, grease and other debris shall not be piled in the warehouse. No rain or snow is allowed to leak into the warehouse and no underground or surface water is allowed to dip into the warehouse.
2.3 Standard, general type brick, special-shaped brick, light brick, refractory fiber products, asbestos products; And refractory mud, ash, castable and other powder, must be piled in the warehouse according to the grade, grade, brick number and masonry order. If limited by the warehouse area, standard clay bricks can be stacked in the open field, but there must be canvas or temporary shed roof to cover rain and snow.
2.4 Before the refractory materials and refractory products are transported to the warehouse, it is necessary to carry out a detailed appearance inspection, if necessary, it will be rechecked with the relevant personnel for physical and chemical indicators, and the unqualified refractory materials and refractory products are counted and placed in a special warehouse, and it is necessary to contact the relevant refractory manufacturers in time to make up for the lack of quantity as soon as possible.
