    mixer/blender?

    I have a coating which i buy from a well known supplier. I have to homogenize the coating when i receive it, because of the settlement of ceramic compounds in the bottom of container. To date i have been using a kitchen blender in the lab for small experiments. Now i am looking for a...

    continuous measurement of cast iron stream

    is it possible to measure the temperature of continuous stream of cast iron from pressurized pouring furnace spout with a non contact IR pyrometer? The accuracy requirement is 5C (plus minus) If yes which sensor should i use? Which company?. Which product? Any help would be greatly...

    continuous measurement of temperature of cast iron stream

    As i mentioned, the idea here is to try to measure the temperature of Pressurized Pouring Furnace Exit Spout continuously.(why not measure the stream before and after pouring , that i cant ask my manager,because he seems to think that needs more labor etc). After doing some research on web and...

    Hardener for Cold Mounting

    During Cold Mounting of some metallurgical samples (cast iron) , i accidently spilled HARDENER in the lab today. I am using Technovit 4004 (hardener and resin ). I have ordered new one and delivery time is after one and half week. Can anybody tell me the recipe of HARDENER (proportions of...

    continuous measurement of temperature of cast iron stream

    is it possible to measure the temperature of continuous stream of cast iron from pressurized pouring furnace spout with a contact sensor ( B or N type ?? ). Non Contact is not an option because of its uncertainty in calibration and difficulties with slag etc. If it is possible , using a...

    color change of BN based coatings

    Acrylic Tint sounds good. I can try that. I will try in the lab first before recommending to our sub supplier. They do the paint job for us on series production level. About temperatures. The coating is applied on the product , then dried at 40C for two hours. When its used in the field , it...

    color change of BN based coatings

    I am using BN hardcoat at the moment. I dont have any problems with the coatings infact. its just that i i have two products with the same coating , and i want to change the color just for visual convenience. I know they have bn lubricoat brand , but i am not sure how different is that from bn...

    Porosity in Cast Irons

    Its just a question :). As i said i want to know general trends. If you want me to tell you the chemistry of the charge, furnace type, tapping temperatures, treatment type, etc then it will definitely become an assignment for me :). As i said i want to know the trends which cause the porosity...

    Porosity in Cast Irons

    What are the process parameters which can cause porosity in cast irons ( Grey,CGI,Ductile)? I want to know general trends during casting (excluding mold design,ingate system, chills etc). I am more intrested in 1- Effect of chemical composition of charge, treatment alloys on porosity (macro and...
