How would I go about creating a auto smelting pickaxe?

package mods.Millarki.common;

import java.util.List;

import net.minecraft.client.renderer.texture.IconRegister;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.item.EnumToolMaterial;

import net.minecraft.item.ItemPickaxe;

import net.minecraft.item.ItemStack;

public class FlamePickaxe extends ItemPickaxe

{

public FlamePickaxe(int par1, EnumToolMaterial par2EnumToolMaterial)

{

super(par1, par2EnumToolMaterial);

}

    /**

    * Return whether this item is repairable in an anvil.

    */

@Override

    public boolean getIsRepairable(ItemStack par1ItemStack, ItemStack par2ItemStack)

    {

        return par2ItemStack.itemID == Millarki.FlameChunk.itemID;

    }

    @Override

public void registerIcons(IconRegister par1IconRegister)

{

itemIcon = par1IconRegister.registerIcon("Millarki:flamepickaxe");

}

}
