    • PURPOSE: A device for testing the adhesion of an insulation-coating layer of a steel sheet is provided to omit a repeated processes for confirming adhesion by bending the surface of a testing piece at various radius curvature at one go, thereby performing a test in a short time. CONSTITUTION: A device for testing the adhesion of an insulation-coating layer of a steel sheet comprises a lower die(10), an upper die(12), recessed portions(20), protruded portions(22), and a driving unit. The upper die is arranged above the lower die and faces the lower die. A testing piece is interposed between the upper and the lower die. The recessed portions are formed in the lower die and bend the testing piece. The protruded portions are formed in the upper die and engaged with the recessed portions by being formed into a form corresponding to the recessed portions. The driving unit is installed in the upper die, thereby pressing the upper die onto the lower die.
    • 目的:提供一种用于测试钢板的绝缘涂层的附着力的装置,以省略通过一次弯曲各种半径曲率的试验片的表面来确认粘附性的重复处理,从而进行试验 短时间。 构成:用于测试钢板的绝缘涂层的附着力的装置包括下模(10),上模(12),凹部(20),突出部(22)和驱动单元。 上模设置在下模上方并面向下模。 测试件插在上模和下模之间。 凹部形成在下模中并使测试件弯曲。 突出部分形成在上模中并通过形成与凹部对应的形式与凹部接合。 驱动单元安装在上模中,从而将上模压在下模上。

    • PURPOSE: A device for protecting oxidation and decarburizing of test piece for jominy test is provided to the oxidation and decarburizing during a test piece thermal process. CONSTITUTION: A device for protecting oxidation and decarburizing of test piece for jominy test comprises a mold(10) and a detachable part(20). The insertion hole(12) is formed on the mold to insert the test piece into the one-side end. The mold is made of a stainless material. The detachable part is combined in the insertion hole of the mold and detachably inserts the test piece to the detachable part. The insert bar is inserted into the guide channel. The test piece is placed in the guide channel. The latching member locates in the floor side of the insertion hole to be vertically protruded at leading end of the insert bar.
    • 目的:在试件热处理过程中,对氧化脱碳装置进行氧化脱碳。 构成:用于保护测试件的氧化和脱碳的装置用于进行测试,包括模具(10)和可拆卸部件(20)。 插入孔(12)形成在模具上以将测试件插入到单侧端部。 模具由不锈钢材料制成。 可拆卸部件组合在模具的插入孔中,并将测试件可拆卸地插入到可拆卸部件上。 插入杆插入引导通道。 将测试件放置在引导通道中。 闩锁构件位于插入孔的地板侧,以在插入杆的前端垂直地突出。
