Abstract
The invention relates to a slag-collecting heat-insulating covering agent, which is applied to slag-collecting heat insulation and covering of metal molten liquid in a casting ladle before casting of ferrous metal casting materials. The use temperature can reach 1600 ℃, the casting defects of slag inclusion, air holes, cracks and the like of the casting can be effectively eliminated, and the casting is nontoxic, tasteless and simple and convenient to operate in the use process.
Description
The present invention relates to a kind of floss collecting agent for temperature isolation, it belongs to oxide process used material improvement in deposite metal in the casting ladle before the metal casting.
At China's ferrous metal casting industry, traditional plant ash is continued to use in the deposite metal insulation before the casting in the casting ladle always, that plant ash has is inflammable, cannot say for sure pipe, environment had shortcomings such as pollution, heat preservation effect difference.Entering the eighties begins to replace plant ash to make coverture with perlite, it is a kind of that the Chinese patent publication number is disclosing of CN1032959A mainly is to be the floss collecting agent for temperature isolation of raw material with the perlite, this coverture has insulation and collection slag function, but still have some problems: 1, perlite content is still too high, satchel tends to cause the damage of watering ladle-lining easily; 2, price is expensive; 3, than heavy, injected volume is big; 4, shading poor performance; 5, when cast needs artificial pushing off the slag, and coverture can not the lifting with the lifting of liquation, and coverture have with liquation fall in the foundry goods may, influence end product quality; 6, the shortcomings such as content that add the iron in the affiliation increase cast steel of brown iron oxide.
Purpose of the present invention changes prescription exactly, improves technology, the by force and coverture of sticking bag of a kind of cheap, high insulating effect, collection slag performance is provided.
Purpose of the present invention realizes in the following manner: coverture is made up of skim agent, heat preserving agent, inserts, exothermic mixture, through sorting, washing, oven dry (drying), mix processing and preparing.
Skim agent among the present invention by: cenosphere (floating pearl), perlite, bentonite are formed; Heat preserving agent is made up of cenosphere (floating pearl), rice husk ash, flyash; Exothermic mixture is made up of cenosphere (floating pearl); Inserts is made up of red sand.Cenosphere (floating pearl) granularity is the 80-120 order, the perlite granularity between the 30-80 order, and the oven dry or dry.The mix ratio of various materials is: cenosphere 10-100%, rice husk ash 0-10%, perlite 0-40%, flyash 0-15%, bentonite 0-20%, red sand 0-5%.
The present invention compares with traditional plant ash, perlite coverture has significant advantage: 1, because the effect of the cenosphere among the present invention, coverture sends slight quick-fried strong sound at molten surface, very fast molten surface form necessarily even, fine and close cover layer, and the heating, this cover layer can the lifting with the lifting of liquation, do not need pushing off the slag, skim conveniently, totally, thereby can guarantee the pure of liquation, improve casting yield; 2, the cover layer of perlite covering is white in color or is light yellow, dazzling, shading poor performance and sticking bag; Cover layer of the present invention is furvous, and good light-proofness is arranged; 3, characteristics such as nontoxic in the use, tasteless, easy to operate and sticking bag.
Describe in further detail below in conjunction with specific embodiment: the floss collecting agent for temperature isolation that is used for grey cast-iron, mixing match is: cenosphere 63%, rice husk ash 5%, perlite 20%, flyash 1%, bentonite 10%, red sand 1%, cenosphere granularity 100 orders, perlite granularity 50 orders, dry or dry, stir to water content 0.25%.Addition is 0.04% of a molten metal, with spades or specific purpose tool coverture is spread on the casting ladle metal bath surface equably, liquation is 8 minutes and 56 seconds from 1400 ℃ of durations of pouring of reducing to 1361 ℃ after testing, 4.08 ℃ of per minute coolings, and collection slag blanket surface tension is 0.3kg/cm
2, be better than plant ash, perlite coverture performance.Below be the present invention and plant ash, the perlite coverture heat-insulating property table of comparisons:
| The solution title | Solution amount | The coverture addition | The coverture title | Cast beginning temperature | The duration of pouring | Cast temperature in latter stage | Cooling rate |
| Grey cast-iron | 1.5(T) | 1.5％ | Plant ash | 1249℃ | 9′56″ | 1360℃ | 6.95 ℃/minute |
| Grey cast-iron | 1.5(T) | 0.30％?? | Perlite | 1428℃ | 9′28″ | 1385℃ | 4.55 ℃/minute |
| Grey cast-iron | 1.5(T) | 0.04％ | The present invention | 1400℃ | 8′56″ | 1361℃ | 4.08 ℃/minute |
The slag-collecting thermal-insulating that the present invention can be widely used in the various ferrous material castings such as grey cast-iron, ball-type cast iron, cast steel covers.
