Abstract
In the present invention, pouring gate cup and pouring tube have refractory and strong matrix produced with quartz sand, ester and water glass and through stirring and moulding. After the matrix is coated in the inner surface with a layer of zircon powder, the pouring gate cup and pouring tube are produced. Compared with available techn, the present invention has simple techn process, short prodn period and reduced cost
Description
The present invention relates to a kind of cast steel with cup and gate spool thereof, be used for cast steel.
At present, when producing big-and-middle-sized steel-casting, because the molten steel consumption is many, thereby the cast ladle that adopts is big, and when pouring cast part, the steel flowing pressure is big, impulsive force is strong, and the duration of pouring is longer, thereby needs that anti-steel stream impacts, heat-resisting refractory brick system cup and gate spool thereof, but refractory brick system cup and gate spool thereof, need fireproof raw material fragmentation, ball milling, batching are mixed system, moulding and last sintering, the production process complexity, the production cycle is long, and be disposable consumption, the cost height.
The purpose of this invention is to provide a kind of production technology is simple, with short production cycle, cost is low a kind of cast steel cup and gate spool thereof.
The object of the present invention is achieved like this:
The matrix adopting ester hardened sodium silicate sand is made.
Ester hardened sodium silicate sand is by 100 parts of quartz sands, liquid soluble glass 4-18 part, and weight is that the organic ester of the 10-15% of liquid soluble glass weight is made.
The granularity of quartz sand is the 40-140 order.
The liquid soluble glass modulus is 2.2-3.4.
Inner surface can have zirconium English powder or coating.
Manufacturing process is: preparation ester hard water glass sand, and quartz sand is added organic ester stir, add liquid waterglass again and stir; With model system type.
After the system type finished 6-9 hour, can be coated with one deck zircon flour coating at inner surface.
Cup and gate spool thereof that the present invention adopts ester hardened sodium silicate sand to make, properties of product can compare favourably with refractory brick system, the raw material wide material sources, technical process is simple, and is with short production cycle, just can use after 6-9 hour, reduce consumption, improved productivity effect, and with low cost.
Structure of the present invention is prolonged the structure with refractory brick cup and gate spool thereof.
Matrix adopting of the present invention is high temperature resistant and have the ester hardened sodium silicate sand of higher-strength to make.With granularity is that 100 parts of 40-140 purpose quartz sands, modulus are the ester hard glass sand of the organic ester preparation of the liquid soluble glass 4-18 part of 2.2-3.4 and the 10-15% that weight is liquid soluble glass weight.Quartz sand adds organic ester and stirs, add again and can shake out after waterglass stirs, the model system type of making of materials such as wooden, plastics or metals after the system type finished 6-9 hour, is coated with one deck at inner surface and has zircon flour coating fast dried, heat-resisting, shock resistance then.
Claims (7)
1, a kind of cast steel is characterized in that: the making of matrix adopting ester hardened sodium silicate sand with cup and gate spool thereof.
2, cast steel according to claim 1 is characterized in that with cup and gate spool thereof: ester hardened sodium silicate sand is by 100 parts of quartz sands, liquid soluble glass 4-18 part, and weight is that the organic ester of the 10-15% of liquid soluble glass weight is made.
3, cast steel according to claim 2 cup and gate spool thereof, it is characterized in that: the granularity of quartz sand is the 40-140 order.
4, cast steel according to claim 2 cup and gate spool thereof, it is characterized in that: the liquid soluble glass modulus is 2.2-3.4.
5, cast steel according to claim 1 cup and gate spool thereof, it is characterized in that: inner surface can have zircon flour coating.
6, cast steel according to claim 1 cup and gate spool thereof is characterized in that manufacturing process is:
A. prepare ester hardened sodium silicate sand, quartz sand is added organic ester stir, add liquid waterglass again and stir;
B. with model system type.
7, cast steel according to claim 6 is characterized in that: after the system type finished 6-9 hour, can be coated with one deck zircon flour coating at inner surface with cup and gate spool thereof.
