Methods for determining foundry molding sand properties 鑄造型砂特性的測(cè)定方法
An on - line measuring method of moisture ratio in molding sand 一種型砂含水率的在線檢測(cè)方法
Semi - compounded molding sand 半合成模砂
Dressing of the molding sand 模砂處理
Test mothod for effective bentonite and effective seacoal content in green molding sand 鑄造用濕型砂有效膨潤(rùn)土及有效煤粉。試驗(yàn)方法
It for consolidating molding sand , such as resin bonded sand , as well as tamping sand , such as clay sand or self hardening sand 本機(jī)主要用于樹脂砂造型時(shí)型砂的振實(shí),也可用于粘土砂造型或自硬砂造型實(shí)砂型的振
Molding process is one of the key sectors of green sand mold casting , the aim of which lies in making the high compactness mold from loose molding sand 摘要造型是濕砂型鑄造生產(chǎn)過(guò)程的核心環(huán)節(jié),它的目標(biāo)在于將松散的型砂緊實(shí)成為高緊實(shí)度的砂型。
It is showed that toughness of phenol resin after modified has been increased , tensile strength and transverse strength of precoated sand and collapsibility of molding sand , which have been improved obviously 改性后的酚醛樹脂韌性增強(qiáng),覆膜砂抗拉強(qiáng)度和抗彎強(qiáng)度明顯提高,型砂的潰散性得到了改善。
The effective cost dust content of molding sand should be determined according to time factors such as the quality of the coal dust , casting size and thickness , pouring temperature , lacing sand or unit sand , and so on 決定型砂中的有效煤粉含量應(yīng)根據(jù)煤粉質(zhì)量的優(yōu)劣、鑄件大小和厚薄,澆注溫度、面砂或單一砂等因素。
This machine fits for mixing moulding sand in large scale and medium scale foundry workshop , as well as system sand for machine moulding , fired mold sand , self - hardening sand , face sand and core sand , also fit for mixing different powder materials for industries of glass , porcelain and fireproofing materials 該機(jī)主要用于大中型鑄造車間型砂的混制,既可混制機(jī)器造型用的單一砂,又可混制干模砂自硬砂面砂和芯砂,也可用于玻璃陶瓷耐火材料等行業(yè)混制各種粉粒狀物料。
Molding sand, also known as foundry sand, is sand that when moistened or oiled tends to pack well and hold its shape. It is used in the process of sand casting.
