Abstract
Floss collecting agent for temperature isolation is a kind of novel ferrous metal cast material, casting metal liquid is had the function of collection slag and insulation.This insulating covering agent is made up of five kinds of main components, through select materials, operation processing and preparing such as pulverizing, mix, its use temperature is 1320 ℃-1450 ℃, and is in use nontoxic, tasteless, dustless, easy and simple to handle, can improve finished product rate 8-10%.
Description
The present invention relates to topped dose of product of a kind of heating slag-collecting thermal-insulating, it belongs to handles used material to deposite metal in the casting ladle before the ferrous metal casting.
At China's ferrous metal casting industry, the hot-metal insulating before the casting in the casting ladle is continued to use traditional plant ash always and is sprinkled into molten iron and is incubated, though the plant ash wide material sources, low price, heat insulation effect is undesirable, and thermosteresis is bigger, and is also influential to production environment; Early eighties, some scholars of China propose to replace plant ash with perlite, the result shows: perlite is done topped dose of surface, casting deposite metal and is had insulation and two functions of collection slag, but still exist some problems: the one, heat loss rate is big, the 2nd, collection slag blanket surface tension is little, the 3rd, collection slag blanket wall built-up is very serious, often causes the damage of watering ladle-lining, so people seek topped dose of a kind of ideal slag-collecting thermal-insulating always.
Purpose of the present invention is exactly in order to address the above problem, and a kind of topped dose with collection slag and heat-insulating property is provided, and a kind of topped dose with collection slag and heat-insulating property is provided, it is little to make it thermosteresis, collection slag blanket surface tension is big, and the collection slag blanket is a wall built-up, raw material easily look for and cost lower.
The present invention is achieved in that by skim agent, heat preserving agent, oxygenant, tensio-active agent, weighting agent and forms, through selecting materials, pulverize, oven dry, mix processing and preparing.
Characteristics of the present invention are: skim agent adopts perlite, heat preserving agent to adopt
Stone and perlite, oxygenant adopt the ferric oxide iron powder, and tensio-active agent adopts fluorite, and weighting agent adopts red sand, with topped dose various compositions: and perlite,
Stone, ferric oxide iron powder, fluorite and coarsely ground foundry sand are broken into powdery or granular its granularity less than three millimeters, and will dry under the temperature more than 20 ℃; The mix proportioning of various auxiliary agents is: perlite 60-65%,
Stone 15-20%, brown iron oxide 0.5-3%, fluorite 5-7%, red sand 10-15%.
Further specify in conjunction with the accompanying drawings, Fig. 2 is the composition synoptic diagram of topped dose of slag-collecting thermal-insulating.1 is the skim agent perlite among the figure, and 2 is heat preserving agent
Stone and perlite, 3 is oxygenant ferric oxide iron powder, and 4 is the tensio-active agent fluorite, and 5 is the weighting agent red sand.
The present invention compares with single perlite covering agent with traditional plant ash has preferably technical performance. One, high insulating effect, heat loss is little, and accompanying drawing 1 is the keeping temprature curve of these three kinds of covering agents, the 2nd, single perlite covering agent keeping temprature curve, the 3rd, keeping temprature curve of the present invention, its test condition all adopts the grey cast-iron molten iron, 125 kilograms casting ladle is from 1450 ℃ of temperature retention times that drop to 1350 ℃; The present invention is 19 minutes and 44 seconds, and single perlite covering agent is 7 minutes and 8 seconds, and the plant ash covering agent is 6 minutes and 11 seconds. Two, collection slag blanket surface tension is big, and the present invention is 0.2kg/cm2, single perlite covering agent is 0.07kg/cm2 Three, can purifying molten iron, pore, the slag inclusion crackle of eliminating foundry goods there is certain effect, can further improve the yield rate of product. Four, nontoxic, dustless, free from extraneous odour, easy to operate in use.
Contriver's a embodiment is: be used for topped dose of the slag-collecting thermal-insulating of grey cast iron, through selecting materials, by following proportioning: perlite 63.5%,
Stone 20%, brown iron oxide 3.5%, fluorite 3%, red sand 10%, separated pulverizing becomes granularity granular less than 3 millimeters, dry under 70 ℃ of temperature then, mix according to the above ratio stirs again, pack with moisture barrier bag through check and to form, its suitable temperature is 1450 ℃, and add-on is the 0.2-0.3% of metal liquid weight, the adding mode: spread casting ladle metal liquid surface equably with spade or with special tool.To drop to 1350 ℃ of soaking times from 1450 ℃ be 19 minutes and 44 seconds to liquid after testing, and its collection slag blanket surface tension is 0.2kg/cm
2, its expansion multiple is 5 times, and pore, slag inclusion, the crackle of eliminating foundry goods had certain effect, has improved finished product rate 8%.
The present invention can be widely used in the various ferrous materials such as cast steel, cast iron, grey cast-iron, spheroidal graphite cast-iron, can be applied to conventional cast, hot investment casting, the various forging types such as continuous casting. Can make special-purpose slag-collecting thermal-insulating covering agent according to casting the dissimilar of material, as: spheroidal graphite cast-iron slag-collecting thermal-insulating covering agent, cast steel slag-collecting thermal-insulating covering agent etc.
